Article Citation - WoS: 20Citation - Scopus: 36Mppt Control of Pmsg Based Small-Scale Wind Energy Conversion System Connected To Dc-Bus(WALTER DE GRUYTER GMBH, 2020-03-13) Dursun, Emre Hasan; Kulaksız, Ahmet AfşinWhile the use of renewable energy systems in electric power generation is increasing more and more, wind energy conversion systems (WECS) receive considerable attention among these. Thanks to the ability of power generation in all wind speed range by controlling the rotor speed, Variable Speed WECSs are more preferred than fixed speed WECSs. When considering small-scale applications in variable speed WECS, Permanent Magnet Synchronous Generator (PMSG) based WECS structures are focus of the interest due to their advantages such as high efficiency and low maintenance costs. The generator must be operated at an optimum speed to obtain maximum power from the WECS. Moreover, different Maximum Power Point Tracking (MPPT) methods can be used to control and determine optimal operating speed. In this paper, WECS configuration consists of PMSG, uncontrolled rectifier, DC link capacitor, DC-DC boost converter and DC-Bus. Capturing the maximum power from WECS and supplying the DC-Bus is performed via tip speed ratio and PI control (TSR-PI) based MPPT method. Moreover, two wind speed profiles having constant and instant changes are created to test the performance of the proposed method. For comparison purposes, perturbation & observation (P&O) based MPPT method is also carried out in here. According to obtained results from this study performed in Matlab/Simulink environment, it is verified that TSR-PI based MPPT method ensures higher power and efficiency for these wind speed profiles by means of a more successful generator speed tracking.Article Citation - WoS: 11Citation - Scopus: 20Sliding Mode Control for Position Tracking of Servo System With a Variable Loaded Dc Motor(KAUNAS UNIV TECHNOLOGY, 2019-08-07) Durdu, Akif; Dursun, Emre HasanIn this paper, the real-time position control of servo system is carried out using sliding mode control (SMC) method based on variable structure control (VSC). As DC Motors are commonly used in many industrial applications and robotics, studies in this paper have are tested on a DC servo system, which is designed and produced by Quanser Inc. Three different types of sliding mode controllers are designed for position control of servo system and, later, performance comparison of DC Motor on Servo system is made. According to results obtained from real-time servo system, it is shown that SMC method is robust against to disturbing effects, variabilities, and uncertainties on the systems. Outstanding part of this paper is that designed controllers are implemented to servo system in real-time with a variable loaded DC Motor. Moreover, this study shows that this control structure can be performed as high performance in the real-time motor control applications.Conference Object Pid-Based Pitch Angle Controller Scheme for Pmsg-Based Wind Energy Conversion System(Institute of Electrical and Electronics Engineers Inc., 2024-12-06) Dursun, E.H.In recent years, the Wind Energy Conversion System (WECS) usage has been increasing with rapid expansion. WECS has a highly nonlinear characteristic and the wind speed is also inherently uncertain. The output power regulation of the WECS at operating conditions above the rated wind speed is one of the subjects of intense interest to researchers. This regulation may be implemented through controlling the pitch angle of the wind turbine. This study presents a PID-based pitch angle controller scheme to realize this purpose in PMSG-based WECS. System configuration and whole controller designs are modeled and created in the simulation environment. In addition, a wind speed profile including both below-rated and above-rated wind speeds is created and the PID-based pitch angle controller is tested in detail for these conditions. According to the results obtained, it is seen that a good control dynamic can be obtained and power regulation is performed effectively by reaching and remaining the pitch angle to needed reference values at above-rated wind speeds. Moreover, with the designed scheme, appropriate adaptation to the changes in different operating points is provided. © 2024 IEEE.Conference Object Optimal Fopid and Rpidd2 Controller Design Using Meta-Heuristic Optimization for Avr System(Institute of Electrical and Electronics Engineers Inc., 2024-11-07) Dursun, E.H.In electric power systems, adjusting the generator voltage through automatic voltage regulator (AVR) systems constitutes a very important problem for ensuring a stable voltage level and reliable electricity distribution. This paper aims to present the optimal design of fractional-order proportional-integral-derivative (FOPID) and real PID plus second-order derivative (RPIDD2) controllers, which have been designed not only to preserve the voltage of the power system within the permitted limits but also enhance its stability. The particle swarm optimization (PSO) has been implemented for the optimal tuning of the controller parameters, thereby achieving enhanced AVR dynamic performance. The search process is performed based on one of the current objective functions, which is a composition of Zwe-Lee Gaing (ZLG) and integral-time absolute error (ITAE) objectives. For this study, the AVR system is modeled in a simulation environment with known standard parameters, and a comparative analysis is conducted. The results of the extensive study demonstrate that the five-parameter FOPID controller exhibits superior dynamic performance, while the six-parameter optimized RPIDD2 controller is capable of achieving even more excellent dynamic performance. It is also shown that more impressive results are achieved than some optimized structures before. Furthermore, a basic robustness analysis is conducted to evaluate the system's response to parameter changes. © 2024 IEEE.Article Citation - WoS: 44Citation - Scopus: 60Second-Order Sliding Mode Voltage-Regulator for Improving Mppt Efficiency of Pmsg-Based Wecs(ELSEVIER SCI LTD, 2020-10-01) Dursun, Emre Hasan; Kulaksız, Ahmet AfşinDriven by the rapidly growing use of wind power, the maximum power extraction of wind energy conversion systems (WECS) has become a significant issue. However, due to the stochastic nature of the wind, employing a nonlinear controller to provide a good tracking performance can be a viable option. In this study, a voltage mode Second-Order Sliding Mode Controller (SO-SMC) is proposed to capture maximum power from the WECSs. Optimum voltages to track are determined via a mechanical sensorless maximum power point tracker (MPPT) approach and these are transferred to the controller. In the proposed method, second-order surface is based on PID type sliding surface. The voltage-mode SO-SMC structure has not been implemented before as a voltage regulator for PMSG-based WECSs consisting of Rectifier and Boost Converter (BC). It is guaranteed that the system can be operated at maximum power point for all wind conditions thanks to the switching of the BC with only a control signal produced by the controller. The proposed method is validated by two different scenarios with different behaviors, that are realistic and step change wind speed profiles ranging from 5 m/s to 12 m/s. In addition, a conventional sliding mode (C-SMC) voltage regulator is designed and performance comparisons are made at these wind speed profiles in terms of output voltage fluctuation, steady-state error and maximum captured average power in steady-state and MPPT efficiency. From these results, it is proven that the proposed controller has a superior performance and it increases efficiency in the extraction of maximum power from WECS with the fast and robust voltage tracking. While MPPT efficiency was increased up to approximately 0.7% for the wind speed profile having the step variations, an increase up to about 1.05% was observed for the realistic wind speed profile.Article Citation - WoS: 9Citation - Scopus: 11Second-Order Fast Terminal Sliding Mode Control for Mppt of Pmsg-Based Wind Energy Conversion System(KAUNAS UNIV TECHNOLOGY, 2020-08-07) Dursun, Emre Hasan; Kulaksız, Ahmet AfşinThis article proposes a new maximum power point tracking (MPPT) controller based on voltage-mode Second-Order Fast Terminal Sliding Mode Control (SO-FTSMC) to obtain better performance in the power extraction from Permanent Magnet Synchronous Generator (PMSG)based Wind Energy Conversion System (WECS). The major objective of the study is the design of SO-FTSMC that can ensure the operation of the system in maximum power reference with higher efficiency, less steady-state error, and voltage fluctuation. Maximum power references are determined by mechanical sensorless MPPT approach. The small-scale WECS configuration incorporates wind turbine, PMSG, uncontrolled rectifier, boost converter, and MPPT controller. SO-FTSMC method has not been performed before as a voltage regulator in such a topology. The proposed controller has been validated for two different wind speed test scenarios in simulation environment, which can be applied effectively to PMSG-based WECS. Moreover, Conventional SMC (C-SMC) is created and then performance of controllers is compared in these wind speed scenarios according to maximum extracted average power, output voltage fluctuation, and voltage error in steady-state, MPPT efficiency, and performance indices. Obtained results indicate that proposed SO-FTSMC-based MPPT controller achieves superior performance.Doctoral Thesis Rüzgar Enerjisi Dönüşüm Sistemlerinin Mppt Kontrolü ile Enerji Verimliliğinin İyileştirilmesi(Konya Teknik Üniversitesi, 2020) Dursun, Emre Hasan; Kulaksız, Ahmet AfşinEnerji talebinin her geçen gün artmasına ve geleneksel enerji kaynaklarına ilişkin açığa çıkan sorunlara yenilenebilir enerji kaynakları temelli güç üretim sistemleri bir çözüm olabilmektedir. Bu kaynaklar arasında ciddi bir potansiyele sahip olan rüzgar enerjisinin kullanımı ise, son yıllardaki gelişen teknoloji sayesinde, dünya çapında hızlı bir büyüme göstermekte ve popülerlik kazanmaktadır. Belirli dönüşüm aşamaları üzerinden enerjinin elde edildiği Rüzgar Enerjisi Dönüşüm Sistemleri (REDS)'nden maksimum gücün daha etkin yakalanabilmesi ve bu sayede de enerji verimliliğinin iyileştirilmesi, en çok önem verilen araştırma konularından biri olmaktadır. Bu noktada literatürde ve endüstriyel uygulamalarda geleneksel yöntemler kullanılabilmiş olsa da, daha etkin ve yenilikçi kontrol stratejileri ve algoritmalara gereksinimler de bulunmaktadır. Bu tez çalışmasında, kontrolsüz doğrultucu ve yükseltici tip DC-DC dönüştürücü içeren güç dönüştürme topolojili kalıcı mıknatıslı senkron generatör temelli REDS'lerden hem maksimum mekanik gücün hem de maksimum elektriksel gücün yakalanması konusu detaylıca ele alınmıştır. Sistemin maksimum güçte çalışması için optimum çalışma noktasının belirlenmesinde çeşitli Maksimum Güç Noktası İzleme (MPPT) algoritmaları kullanılmış ve ayrıca bu noktaya sistemi getirmek amacıyla önceden bu bakış açısıyla uyarlanmamış olan çeşitli kayan kipli kontrolörler de tasarlanmıştır. Bunlara ek olarak, güncel optimizasyon tekniklerinin MPPT metotlarına entegre edilmesi üzerine de çalışılmıştır. Kaotik temelli parçacık sürü optimizasyonunun iki türevinin ayrı ayrı optimum ilişki temelli yöntemle birleştirildiği ve kayan kip tabanlı kontrolörün benimsendiği iki adet hibrit tümleşik maksimum güç yakalama çerçevesi de türetilebilmiştir. Oluşturulan farklı rüzgar hızı değişim profilleri altında tüm testler simülasyon ortamında doğrulanmış olup, kontrolörler için kararlılık analizleri de detaylı olarak sunulmuştur. Tüm bu çalışmalar neticesinde, maksimum güç noktasının daha doğru ve kesin olarak tespitinin yanı sıra daha az sürekli hal hatası ve gerilim dalgalılığına ulaşılması sayesinde daha üstün bir izleme performansıyla MPPT sistem verimliliğine katkı sağlandığı görülmüştür.Article Analysis of Performance Coefficients in Maximum Electrical Power Extraction From Stand-Alone Wind Energy Conversion System(Konya Teknik Univ, 2022-12-03) Dursun, Emre HasanIncreasing performance and improving efficiency in maximum power extraction from Wind Energy Conversion Systems (WECS) is a quite important research topic. Today, in the large-scale WECS, it is widely aimed to extract the maximum mechanical power from the wind turbine using the Maximum Power Point Tracking (MPPT) unit. Similarly, it can also be targeted to achieve maximum mechanical power in small-scale WECS applications. However, losses occur in structural subsystems and electrical subunits located in WECS. Due to these losses, the overall system efficiency decreases and the characteristic of the system is also affected. The operation of these systems can also be performed via maximum electrical output power extraction, which is one of the most up-to-date ideas. Thus, the overall WECS rather than the wind turbine can be optimally controlled. Eventually, maximum electrical power tracking (MEPT) based designs can provide higher power extraction with higher efficiency than MPPT-based ones. In this paper, considering the system operating concepts with MPPT and MEPT for a stand-alone Permanent Magnet Synchronous Generator (PMSG) based WECS, the changes in performance coefficients at defined focus points in terms of system efficiency are evaluated. Technical and theoretical comparative analyzes are also made for each specific wind speed between 8m/s and 12m/s.Conference Object Citation - Scopus: 2Pid and Pid-F Controller Design Based on Particle Swarm Optimization for Automatic Voltage Regulator System(Institute of Electrical and Electronics Engineers Inc., 2024-09-21) Dursun E.H.; Dursun, Emre HasanThis study presents the implementation of two distinct controller designs, optimized with particle swarm optimization (PSO), for the conventional automatic voltage regulator system (AVR). These designs are proportional integral derivative (PID) controller without filter, which is known as ideal in the literature, and PID-F controller with filter. This study aims to identify the optimal parameters of controllers by employing the PSO algorithm. While a variety of objective functions are considered in the study, a current objective function, ZLG+ITAE, which represents a combination of Zwe-Lee Gaing (ZLG) and the integral-time absolute error (ITAE) objectives, is also employed in the tests. Thus, five different controllers are developed for the objective functions used. The study is initially modeled in a simulation environment with known standard AVR system parametric data. A comparison of the obtained performance data reveals that the GLZ+ITAE objective function yields more successful results. The system is evaluated both transiently and in steady state, according to specific criteria. The results demonstrate that more optimal dynamic response can be achieved. Furthermore, the comprehensive results illustrate that the four-parameter PID-F controller structure optimized via PSO can yield improved outcomes compared to those of the ideal PID. © 2024 IEEE.Article Application of Fuzzy Logic Control for Enhanced Speed Control and Efficiency in PMSM Drives Using FOC and SVPWM(IOP Publishing Ltd, 2025-07-01) Oztok, Mahmut Furkan; Dursun, Emre HasanPMSMs (Permanent Magnet Synchronous Motors) are favored in industrial systems requiring fast dynamic response and precision, thanks to their high efficiency and torque-to-inertia ratio. To fully leverage these motors, advanced control techniques like Field-Oriented Control (FOC) are essential, as they decouple torque and flux. However, traditional FOC systems often use PI controllers, which suffer from limited adaptability and challenging tuning processes, especially in applications demanding quick responses. To overcome these limitations, the study compared fuzzy logic-based speed control strategies. Three control structures were modelled in MATLAB/Simulink, integrating SVPWM for enhanced performance: traditional FOC with PI controller, FOC with single-input Fuzzy Logic Controller (FLC), and FOC with two-input FLC (FLC2). The simulation results clearly demonstrated FLC2's superior performance, achieving only 0.53% overshoot and a 0.08-second settling time. Quantitative metrics like IAE, ITAE, and ISE further validated FLC2's superiority over conventional control structures. These findings prove that, particularly the two-input FLC, offers a robust and high-performance alternative to traditional PI control in industrial automation, electric vehicles, and energy-efficient motor applications. With its simplicity, adaptability, and improved control performance, FLCs can play a significant role in next-generation smart motor drive technologies.
