【摘要】：在高性能的电气传动系统中,永磁同步电机因其特有的优势而被广泛的应用,传统的机械式传感器已不能满足控制系统的要求,而无位置传感器控制技术能消除机械传感器带来的不足。本文首先对脉振高频信号注入法进行理论分析,设计出PMSM位置与速度估计系统;其次,采用高频信号注入无位置传感器方法,在MATLAB/Simulink中搭建无位置传感器控制系统模型并仿真;最后,在设计的基于dSPACE的永磁同步电机控制系统上验证了零低速无位置传感器方法。仿真及实验结果表明了脉振高频信号注入低速无位置传感器控制系统具有良好的运行效果。
[Abstract]:Permanent magnet synchronous motor (PMSM) has been widely used in high performance electrical transmission system because of its unique advantages. Traditional mechanical sensors can not meet the requirements of the control system. The position sensorless control technology can eliminate the shortage of mechanical sensor. In this paper, the position and velocity estimation system of PMSM is designed by theoretical analysis of high frequency signal injection method of pulse vibration. Secondly, the position sensorless control system model of position sensorless control system is built in MATLAB/Simulink by high frequency signal injection without position sensor. Finally, the zero low speed sensorless method is verified on the PMSM control system based on dSPACE. The simulation and experimental results show that the high frequency pulse signal injection low speed position sensorless control system has a good operation effect.
