永磁同步电动机伺服系统的研究

Research on Servo System of PMSM

永磁同步电动机(PMSM)是一个复杂耦合的非线性系统。分析研究了永磁同步电动机数学模型和矢量控制(VC)原理,在Matlab/Simulink环境下,建立了永磁同步电动机双闭环矢量控制系统模型。仿真结果表明,该系统具有较好的启动特性和良好的抗扰动性,同时也说明了该仿真模型的正确性和有效性。

The permanent magnet synchronous motor is a non-linear system with complex coupling. In the analysis of permanent magnet synchronous motor （PMSM） mathematical model and vector control principle, to establish a permanent magnet synchronous motor vector control system simulation model based on the Matlab/ Simulink environment, and builds the models of PMSM dual close loops vector control system. The simulation results show that the control system has better performance, proving the validity and effectiveness of the simulation model.
