Vector Control Strategy of Permanent Magnet Synchronous Motor Based on Model Reference Adaptive

针对永磁同步电机矢量控制中存在的稳定性差、系统精度较低等问题,提出了一种基于模型参考自适应系统的永磁同步电机矢量控制策略。通过选取恰当的自适应律提高对转速和转子位置估计的准确度,并引入滑模控制策略对矢量控制系统进行优化。仿真结果表明,这个方法可以有效降低超调量和抖振,提高系统的稳定性。

Aiming at the problems of poor stability and low system accuracy in the vector control of permanent magnet synchronous motors,a vector control strategy for permanent magnet synchronous motors based on model reference adaptive system is proposed.The accuracy of the estimation of speed and rotor position is improved by selecting the appropriate adaptive law,and the sliding mode control strategy is introduced to optimize the vector control system.The simulation results show that this method can effectively reduce the overshoot and chattering,and improve the stability of the system.
