说明：  针对双闭环矢量控制的三相电压型 PW M 整流器难以用准确的数学模型描述、以及通过其简化的数学模型求得的PI参数需要实验整定的问题 ，提出了基于模糊 P I控制器的新型智能化控制方法。与传统的Pl控制方法相比。该方法不仅实现了PI参数的自整定。还使系统具有更好的响应性能、更高的稳定性及鲁棒性。利用 M atlab／Sim ulink 工具箱建立了基于模糊 P l控制器的整流器仿真模型，并通过仿真实例对此设计方法进行了实验验证。
(In order to solve the problem that it is difficult to describe the three-phase voltage type PWM rectifier with double closed-loop vector control by accurate mathematical model and the PI parameters obtained by its simplified mathematical model need to be adjusted by experiment, a new intelligent control method based on Fuzzy PI controller is proposed. Compared with the traditional PL control method. This method not only realizes the self-tuning of PI parameters. It also makes the system have better response performance, higher stability and robustness. Using Matlab / Simulink toolbox, the rectifier simulation model based on Fuzzy PL controller is established, and the design method is verified by simulation example.)
