基于模糊PI的永磁同步电机矢量控制算法

A Fuzzy Predictive Control Algorithm in the Permanent Magnet Synchronous Motor Vector Control

在永磁同步电机的矢量控制中,速度环和电流环存在动态响应不足、PI参数难以调整等问题。通过对模糊PI算法深入研究,本文设计了一种模糊PI控制器,取代了传统的速度环PI控制器,仿真结果表明,采用模糊PI控制器的永磁同步电机调速响应更快,同时具备更好的动静态性能和抗干扰能力,体现该方案的可行性和正确性。

In the vector control of permanent magnet synchronous motor, the velocity loop and the current loop have insufficient dynamic response, PI parameter is difficult to adjust and so on. In this paper, a fuzzy PI controller is designed to replace the traditional speed loop PI controller. The simulation results show that the permanent magnet synchronous motor with fuzzy PI controller is faster and has a faster response speed. Better dynamic and static performance and anti-interference ability, to mention the feasibility and correctness of the program.
