| 摘 要： | 考虑到永磁直线同步电动机(PMLSM)在重复运行过程中会受到由端部效应引起的周期性推力波动和周期性摩擦力以及其他非周期扰动,为提高跟踪精度,文章提出了一种重复控制和滑模变结构控制相结合的PMLSM跟踪控制策略.设计了二阶滑模速度、电流控制器,用于抑制非周期性扰动.滑模控制率采用超螺旋算法,该算法简单易实现,并且能够有效抑制抖动现象.设计PD+重复位置控制器,用于抑制跟踪过程中的周期性扰动.仿真结果表明该策略具有较高跟踪精度,同时具有响应速度快、鲁棒性强的特点.

| Abstract: | Because Permanent Magnet Linear Synchronous Motor(PMLSM) is affected by the periodic thrust fluctuation caused by the end effect,the periodic friction and other aperiodic disturbances during operating.To improve the tracking precision,the tracking strategy of PMLSM based on sliding mode control and repetitive control was proposed in this paper.The speed controller and the current controller based on 2-order sliding mode were designed to restrain kinds of aperiodic disturbances.Supper-twisting algorithm was ... |
