中文摘要：
针对微分滑模控制降低系统稳定性和滑模控制固有的抖振问题，并对变指数趋近律滑模控制存在的不足进行改进，研究了一种新型积分滑模控制器，并将它应用于永磁直线同步电机（PMLSM）伺服系统的速度环控制中。通过MATLAB／Simulink及MATLAB编程搭建PMLSM伺服系统仿真模型。仿真结果表明，与传统PI和变指数滑模控制相比，新型滑模变结构控制器不仅能有效抑制滑模变结构的抖振，还增强了控制系统的快速性和鲁棒性。这为进入下一步系统平台试验提供了理论和仿真依据。
英文摘要：
Aiming at the problems of differential sliding mode control reduces system stability and sliding mode control inherent chattering characteristic, and improved the weakness of variable exponent reaching law sliding mode control. A new integral type sliding mode controller and applies to the speed loop in servo system of permanent magnet linear synchronous motor was investigated. The simulation model of permanent magnet synchronous linear motor servo system based on space vector control was established by MATLAB/Simulink and M language. Compared with the traditional PI and variable exponential sliding mode control, the simulation results showed that the new sliding mode controller not only effectively restrain the chattering of the sliding mode variable structure, but also enhanced the rapidity and robustness of the control system. That provided theoretical and simulation basis for the next experiment of the system platform.
