基于模糊自适应的永磁同步电机矢量控制系统

Self-adaptive fuzzy controller of vector controlled permanent magnet synchronous motor

提出了一种基于模糊自适应的永磁同步电机(PMSM)矢量控制系统的速度控制器的方案。模糊自适应控制器由模糊逻辑控制器和传统的PI控制器组成,采用模糊自适应控制器的输出对传统PI参数进行实时调整,使其具有模糊逻辑在处理不确定信息方面的能力和PI控制在线性系统中的良好性能。Matlab的仿真结果表明,采用模糊自适应建立的永磁同步电机的速度控制器,在系统参数发生变化或者受到外部扰动的情况下,PMSM矢量控制系统具有较好的动态响应特性。

The implementation of self-adaptive fuzzy controller for speed control of a permanent magnet synchronous motor （PMSM） was proposed. The controller was consists of a fuzzy logic controller term and a traditional PI control term. The output of the fuzzy adaptive controller was used to adjust the traditional PI parameters in real time, which made it have the ability of fuzzy logic to deal with the uncertain information and good performance of the PI control in the linear system. The simulation results of Matlab showed that the dynamic characteristics of the proposed controller was reliable under the condition of parameter variations and external disturbance.
