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)

When faced with the task of solving a partial differential equation computationally, one quickly realizes that there is quite a number of different methods for doing so. Among these are the widely used finite difference, finite element, and finite volume methods, which are all techniques use
