According to the mutability and uncertainty of the wind speed and the nonlinearity and strong coupling characteristics of switched reluctance generators, proposes a method based on fuzzy adaptive PID closed-loop controller to optimize the output voltage. Describes the operating principle of the switched reluctance generator system and fuzzy adaptive PID control principle, and by using Matlab/Simulink tools makes simulation and comparative analysis on the output voltage of switched reluctance generators under the control of conventional PID and fuzzy adaptive PID. The experimental results show that the fuzzy adaptive PID closed-loop control has higher output voltage control accuracy, better dynamic performance as well as strong anti-interference ability and robustness.
