基于内模控制的永磁直线同步电动机速度控制

基于内模控制原理,在建立永磁直线同步电动机(PMLSM)非参数模型基础上,设计了PMLSM内模控制器.通过理论分析和仿真确定了决定内模控制器性能的参数取值范围,并进行了实验验证.结果表明,PMLSM内模控制系统跟踪调节性能好、鲁棒性强,能消除不可测干扰的影响.

Speed Control of PMLSM Based on Internal Model Control

According to the internal model control (IMC) theory, non-parameter model of the permanent magnet linear synchronous motor (PMLSM) was made, then a novel IMC controller of PMLSM was designed. The optimal parameters of IMC was adjusted and decided by theory analysis and simulation. The simulating and experimental results show that the proposed controller provides perfect dynamic response performance in both reference tracking and disturbance rejection,moreover, it is robust to external disturbance.
