Control strategies for extracting the three-phase reference currents for shunt active power filters are compared, uating their performance under different source conditions with PI and Fuzzy Controllers in MATLAB/Simulink environment When the supply

针对三种不同脉冲编码信号的模糊函数进行了设计。矩形脉冲信号，线性调频信号，相位编码信号。(The fuzzy function is designed for three different pulse coding signals.Rectangular pulse signal, linear frequency modulation signal, phase coded signal.)
