Realization of Fuzzy Self-Tuning PID Controller in Solar Energy Maximum Power Point Tracking

This paper adopted the incremental conductance method and introduced the fuzzy self-tuning PID controller to eliminate the oscillation of PV power at the maximum power point and achieved a better tracking effect of power based on the chip of TMS320LF2407A.The practice results prove that it can basically eliminate the oscillation of the output power of photovolatic cells at the maxinun power point,improve the efficiency and reduce the fluctuation.
