摘　　要：永磁同步电机的无位置传感器控制系统由于具有安装简单、容易实现等优点,在许多领域得到广泛应用。文中主要分析了永磁同步电机的无位置传感器控制系统,使用磁通观测法实现了对转子角度位置的测量,并后续使用锁相环和状态观测器两种方法对所得角度进行处理。使用Matlab中的Simulink仿真工具对整个控制系统进行仿真,对仿真结果进行分析,验证了文中所用无位置算法的可行性和实用性。Sensorless control system for permanent magnet synchronous motor （PMSM） has been widely used in many areas for its simple installing and easy realizing advantages. This paper mainly analysed sensorless control system of PMSM, estimated the angel of rotor and speed based on flux observation initially, PLL and state observer were used to obtain the accurate angle. Used Simulation toolbox design of Matlab to implement the simulation of control system and analyzed the simulation results. The results verified the correctness and feasibility flux observation method that used in paper.
