“…The fuzzy controller is matched to a value between -1 and 1 through two gain values GE and GCE for fuzzification, and an output value (∆D) is calculated using a membership function and a rule base. Equation (24) shows the output value by the center of gravity method (COG). The calculated output value controls the duty ratio of PWM for MPPT control through defuzzification gain (GU).…”

“…It also has a limit in improving tracking speed and in tracking accuracy because it varies the voltage or current to a fixed size [22]. To solve this problem, methods using artificial intelligence control such as PI control [1,[23][24][25], fuzzy control [26][27][28], and neural network [29,30] were presented. PI control has a problem with fixed gain values, and neural networks suffer from poor response performance if sufficient learning is not achieved.…”

This paper presents an optimal design of a fuzzy control rule base for tracking the maximum power point of a photovoltaic (PV) system. Fuzzy control is used for the maximum power point tracking (MPPT) of PV systems because it has the advantage of processing nonlinear systems. The rule base of fuzzy control depends on the user or designer’s experience and determines the fuzzy control’s performance. In this paper, we divide the MPPT state of the PV system into four cases according to the operating conditions, and propose the rule base design of the fuzzy control according to each case. The proposed method in the paper tests the MPPT performance using artificial lighting and compares the results with the conventional control method (proportional and integral (PI) and perturbation & observation (P&O) method) to prove its effectiveness.

“…Her PV panelin kendine özgü karakteristiği vardır. Genel olarak, PV sisteminin tümünün maksimum verimle çalıştığı ve maksimum çıkış gücünü ürettiği V-I veya V-P eğrisinde MPP adı verilen tek bir nokta vardır (Anil, 2013).…”

Maksimum güç noktası izleyici (MPPT), fotovoltaik (PV) sistemlerde, DC-DC dönüştürücülerin anahtarlama görev süresi (duty cycle) değiştirerek çıkış gücünü maksimize etmek için kullanılır. Bu çalışmada, PV sistemler için parçacık sürü optimizasyon (PSO) ve PID tabanlı MPPT algoritması sunulmuştur. Önerilen yöntemin başarısını test etmek amacıyla elde edilen sonuçlar, klasik PID denetleyici ve PV sistemlerde yaygın kullanılan değiştir ve gözle (P&O) yöntemlerinin sonuçları ile karşılaştırılmıştır. Çalışmalar Matlab/Simulink ortamında gerçekleştirilmiştir. Önerilen denetim yapısının hem geçici hem de kararlı durumlarda diğer yöntemlere göre daha başarılı olduğu görülmüştür.

“…Each type of PV module has its own specific characteristic. In general, there is a single point on the V-I or V-P curve is called as MPP, at which the entire PV system operates with maximum efficiency and produces its maximum output power [10]. This point can be located a PV system with MPPT controller has been shown in block diagram of Maximum Power Point Tracker, frequently referred to as MPPT, is an electronic system that operates the PV modules in a manner that allows the modules to produce all the power they are capable of MPPT is not a mechanical tracking system that "physically moves" the modules to make them point more directly at the sun.…”
