The research on maximum power point tracking in solar cell based on fuzzy PID control

Based on the advantages and disadvantages of some common methods which are used to trace the maximum power of solar cells, a novel fuzzy PID control method which can rapidly respond to changes in the external environment and effectively eliminate the oscillation phenomena near the power points is put forward after the properties of solar cell are carefully discussed. Every unit circuit is stimulated and the result verified the good performance of the proposed method.
