| Abstract: | PWM rectifier is a system of non-linear and the system parameter easily changed.The PI control method is usually used, but it is sensitive to system parameter and the dynamic response is slow.So the PI control method couldn’t satisfy the need.Based on the double closed loop control,the fuzzy PI is applied to three-phase PWM voltage source rectifier.A three-phase PWM rectifier simulation model based on MATLAB/SIMULINK is established.The simulation results demonstrate that the three-phase PWM rectifier has unity power factor and favorable dynamic performance.So the feasibility and validity of the proposed method is verified. |
