Abstract :
The characteristics of photovoltaic array are relate to some environmental factors such as temperature and radiation intensity, load and the aging degree of the battery. Then the maximum power point will change with them. We can improve the tracking velocity and accuracy by using finite impulse response(FIR) filter predictive control algorithm and hysteresis control method. A simulation system based on MATLAB/simulink is developed. The result shows that the system could trace the maximum power point of the photovoltaic array in time and achieve the maximum power point tracing control rapidly and stably.
