Abstract
It is difficult to realize the three-phase voltage PWM rectifier with the traditional PI control strategy, and with the increasing requirements for the performance of the rectifier, the traditional PI control in performance has been difficult to achieve the desired effect, so this paper proposes a new double closed-loop control strategy. The original voltage outer loop PI control is changed to fuzzy PI control while the inner loop current control still uses feedforward decoupling control strategy. Compared with the traditional PI control method, the proposed method not only realizes the self-tuning of PI parameters, but also makes the system have better response performance, higher stability and robustness. Matlab/Simulink toolbox is used to build a rectifier simulation model based on fuzzy PI control, and then the design method is verified by simulation experiments.
