Research of Solar Tracking Controller for PV Panel Based on Fuzzy Logic Control

Abstract

The paper presents the concepts of solar tracking controllers for photovoltaic panels based on the fuzzy control law. The controller uses a microcontroller and algorithm based on fuzzy logic. In this study, a triangle type is seen to be appropriate as a membership function, so that the microcontroller can solve problems faster. The fuzzy logic controller uses a MISO fuzzy system with two inputs of the ADC signal from the light sensor and one output of the PWM duty cycle rate. Membership functions and fuzzy control systems are created via a MATLAB program, thereby checking the correctness of fuzzy logic controllers.
