【摘要】：在高性能的電氣傳動(dòng)系統(tǒng)中,永磁同步電機(jī)因其特有的優(yōu)勢(shì)而被廣泛的應(yīng)用,傳統(tǒng)的機(jī)械式傳感器已不能滿足控制系統(tǒng)的要求,而無位置傳感器控制技術(shù)能消除機(jī)械傳感器帶來的不足。本文首先對(duì)脈振高頻信號(hào)注入法進(jìn)行理論分析,設(shè)計(jì)出PMSM位置與速度估計(jì)系統(tǒng);其次,采用高頻信號(hào)注入無位置傳感器方法,在MATLAB/Simulink中搭建無位置傳感器控制系統(tǒng)模型并仿真;最后,在設(shè)計(jì)的基于dSPACE的永磁同步電機(jī)控制系統(tǒng)上驗(yàn)證了零低速無位置傳感器方法。仿真及實(shí)驗(yàn)結(jié)果表明了脈振高頻信號(hào)注入低速無位置傳感器控制系統(tǒng)具有良好的運(yùn)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.
