摘要
针对直线永磁同步电机提出了一种基于负载推力观测器的新型滑模变结构控制,从而实现对推力扰动的补偿,且大大削弱了推力纹波及系统的抖振;在滑动模态中引入积分环节来进一步消除系统的稳态误差和系统抖振。仿真结果表明该方案能提高系统对参数摄动和外在阻力扰动的鲁棒性。
A new sliding mode variable structure control is designed with a load thrust observer for the Linear Permanent Magnet Synchronous Motor (LPMSM), thus cornpensaing the disturbance and effectively minimizing the system chattering. Introduce an integral action in the sliding mode, further so as to remove the system error and chattering. Simulations verify that this control scheme can make the system to have strong robustness to parameter variations and external disturbances.
