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 P I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 P l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。(It is difficult to describe the three-phase voltage type PWM rectifier with double closed-loop vector control by accurate mathematical model and to obtain it by its simplified mathematical model For the problem that PI parameters 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 does not Only the self-tuning of PI parameters is realized. It also makes the system have better response performance, higher stability and robustness. Using Matlab / SIM ULINK toolbox to build The simulation model of rectifier based on Fuzzy PL controller is presented, and the design method is verified by simulation example)
