永磁同步电机数学模型存在着非线性和强耦合的特性,针对永磁同步电动机伺服系统的高性能控制要求,提出一种基于内模控制技术的永磁同步电机控制策略。采用内模控制原理进行速度环的设计,将电流环及PMSM模型整体看作被控过程,建立了被控过程的简易数学模型。基于Matlab/Simulink仿真平台,对基于内模控制的永磁同步电机控制系统进行了仿真分析,试验结果表明,与传统的矢量控制方法相比,该控制策略具有更良好的控制特性。

PMSM mathematical model exists nonlinearity and strong coupling characteristics, a internal model control strategy was proposed for the high-performance requirements of PMSM servo system to strengthen the anti-disturbance capability and improve the system robust-ness. Using internal model control principle design speed loop, The current loop and PMSM model seen as a whole controlled process, establish a simple mathematical model of the controlled process. Simulation analysis, based on endometrial control of permanent magnet synchronous motor control system based on Matlab/Simulink simulation platform, the results showed that compared with the traditional vector control method, the control strategy has a better control characteristics.
