低成本的永磁同步电动机控制系统仿真

摘要

介绍了基于开关型霍尔元件的永磁同步电动机矢量控制系统的组成原理和转子角度估算的几种方法.在MATLAB/Simulink环境下搭建了基于以上角度估算方法的永磁同步电动机矢量控制仿真模型.通过运行仿真模型比较了基于这些方法下永磁同步电动机的运行性能.%The theory and several methods to estimate the rotor angle of the permanent magnet synchronous motor (PMSM-) vector control system were introduced based on switched Hall,and the permanent magnet synchronous motor vector control simulation model was built based on estimation method above in MATLAB / Simulink environment. The performance of permanent magnet synchronous motor running under these methods were compared by running the simulation model.
