Research on Sensorless Vector Controlling System of Permanent-Magnet Synchronous Motor Based on DSP

阐述了采用滑模控制的无位置传感器矢量控制原理,应用于永磁同步电机无位置传感器调速系统的方案。采用坐标变换,建立了控制系统数学模型并进行了仿真分析,针对电机定子电流对转子位置估算角度的影响进行了分析并提出了解决方法。

This paper describes the principle of dislocation sensor vector controlling by slip form and scheme and the scheme of adjusting speed of dislocation sensor of permanent-magnet synchronous motor. The mathematics model of controlling system is founded and simulated by coordinate transfer. The influence of the stator current on the angle of estimating rotor position is analyzed and the method to resolve it is presented.
