基于MATLAB/simulink搭建的应用于永磁同步电机（PMSM）的无传感器控制，主要是基于矢量控制，采用滑模转速和转子位置观测器取代传统的位置传感器，最终实现对PMSM的控制(The sensorless control based on MATLAB/simulink for permanent magnet synchronous motor (PMSM) is mainly based on vector control. Instead of the traditional position sensor, the sliding mode speed and rotor position observer are used to control the PMSM.)
