中文摘要:三相电压型 PWM 整流器一般采用传统双闭环PI控制策略,而PI控制参数是在特定条件下整定的,在负载变化和扰动较大的情况下系统适应性差,难以取得良好的控制效果。结合自适应的控制思想,在PI控制的基础上,提出了一种新型的控制方法,即在电压外环采用模糊自适应PI控制,电流内环采用前馈解耦的控制策略。仿真结果表明这种控制方法适应性强,具有良好的动态性能。

Research on Three-phase PWM Rectifier Based on Fuzzy Adaptive Control
Abstract:As the three-phase voltage-type PWM rectifier (VSR) using traditional PI control strategy is difficult to obtain good control effect in the case of large disturbance and load a broad range of mutations.Basis on the traditional double closed-loop PI control strategy,combined with adaptive control ideas,a new control method is proposed in this paper,which is that PI control and fuzzy control will be applied to outer loop control of the voltage,and the inner loop current control use feed forward decoupling control strategy.The simulation results show that the control method is fast response and strong adaptability, and has good dynamic and static characteristics.
