基于模型预测控制的永磁同步电机电流控制技术综述

Review on Permanent Magnet Synchronous Motor Current Control Techniques Based on Model Predictive Control

永磁同步电机(PMSM)驱动控制技术的性能直接决定着整个电机驱动系统的性能。由于模型预测控制(MPC)技术可以对多输入多输出(MIMO)系统进行滚动优化控制,且容易施加约束,因此基于MPC的电机驱动技术正逐渐受到关注。回顾并总结了近年来国内外学者在基于MPC的PMSM电流控制方面所做的研究,并对现有技术中的基于单矢量、双矢量以及三矢量的电流控制技术进行了建模并进行了电流输出波形分析。最后综合比较了现有技术的优缺点,并讨论了现有技术尚存的一些问题和未来发展的主要方向。

The performance of drive control technology for permanent magnet synchronous motor (PMSM) directly determined the performance of the whole motor drive system.Motor drive technology based on model predictive control (MPC) was gaining attention due to the fact that MPC technology could perform rolling optimization control for the multiple-input multiple-output (MIMO) system and was easy to impose constraints.The researches done by domestic and foreign scholars on the current control of PMSM based on MPC in recent years were reviewed and summarized.Meanwhile,the current control technology based on single vector,double vectors and three vectors in the MPC was modeled and the current output waveform was analyzed.Finally,the advantages and disadvantages of current technologies was compared comprehensively,and some problems existing in the current technology and the main development direction in the future were discussed.
