摘要
永磁同步电机控制中采用传统滑模变结构控制器时,抖振难以消除,为此在指数趋近律滑模控制的基础上,采用幂次函数代替传统开关符号函数,设计新型的趋近律速度滑模控制器。应用矢量控制方法,建立了永磁同步电机的数学模型,并在Matlab/Simulink环境下搭建了仿真系统模型并进行验证。仿真结果表明,改进型滑模变结构控制永磁同步电机,速度和电磁转矩响应速度快、超调小、抖振明显削弱,验证了改进算法的有效性。
An improved speed controller with shdmg moOe was aeslgneo oy u^ln8 pt）wc the traditional switch symbol function, because it was difficult to eliminate the chattering when designed a permanent magnet synchronous motor（PMSM） controller with the traditional sliding mode variable structure. The mathematical model of PMSM was built based on vector control strategy, which was built and simulated in Matlab/Simulink environment. The simulation results showed that the control system of PMSM built by im- proved sliding mode had quick velocity response and electromagnetic torque response with less overshoot and significantly weakened chattering, which verified the efficiency of the improved algorithm.
