基于DSP的PMSM无位置传感器控制系统研究

Research on Control System of PMSM without Location Sensor Based on DSP

永磁同步电机(PMSM)在电动汽车行业相对于其他电机有较大的竞争优势,永磁同步电机具有启动牵引力大、功率效率高、控制性能好、体积小、噪声小等特点,所以永磁同步电机成为了很多汽车制造商的选择。利用MATLAB的Simulink对永磁同步电机进行仿真,然后在DSP进行软件和硬件的设计。

Permanent magnet synchronous motor(PMSM)has a great competitive advantage over other motors in the electric vehicle industry.Permanent magnet synchronous motor has the characteristics of large traction,high power efficiency,good control performance,small size,and small noise.Therefore,permanent magnet synchronous motors have become the choice of many car manufacturers.Using MATLAB's Simulink,the permanent magnet synchronous motor is simulated,and then the software and hardware are designed in DSP.
