摘要：传统的永磁同步电机矢量控制系统采用比例积分（PI）速度控制器，其动态响应性能比较差。针对这一问题，设计了一种基于Fuzzy-PID的多模态自适应控制器，作为永磁同步电机矢量调控系统的速度调节器。这种控制器可以利用模糊逻辑处理不确定信息，对速度控制器的输出进行实时校正。仿真结果表明：利用该控制器建立的矢量控制系统不仅结构简单，而且具有良好的动、静态特性。

Abstract: Traditional vector control system adopts proportional-integral speed controller for permanent magnet synchronous motor(PMSM) and its dynamic performances become worse. In order to solve this problem, a kind of Fuzzy-PID multistate self-adjusting controller was designed. It was used as a speed adjuster for the vector control of the PMSM. The uncertain information was handled using the fuzzy logic, then the output of the speed controller was updated real-timely. Results of simulation show that vector control system based on this controller not only has the simple configuration, but also has the steady-state precision and dynamic performance.
