摘要
针对电网谐波,在PI控制基础上加入模糊控制,根据采样误差实时调整PI参数,从而减小控制误差,提高并网电流质量。仿真比较了在电网含有谐波情况下,PI控制、重复补偿PI控制和PI模糊控制的电流输出结果。
For gird harmonic,PI control is combined with fuzzy control.PI parameters are adjusted in real time according to the sampling errors,to decrease the control error and improve the grid current quality.Simulation is carried to compare the grid current output with three control methods such as PI control,PI&repeat control and PI&fuzzy.
