交流永磁直线同步电机伺服系统的预见前馈补偿

Preview feedforward compensation of AC permanent magnet linear synchronous motor servo system

介绍了高精度、微进给永磁直线交流同步电机（ＰＭＬＳＭ）伺服系统的ＩＰ位置控制后，提出了对该系统的最优预见前馈补偿，以提高系统的跟踪性能。为了补偿负载扰动，进一步增强系统的鲁棒性，设计了负载扰动力观测器来进行前馈。仿真实验结果证明了所提出方案的有效性。

After presenting IP position control for a high-precision micro-feed AC permanent magnet linear synchronous motor(PMLSM) servo system, a method of optimal previewfeedforward compensation for this system to improve the tracking performance is presented.To compensate the load disturbance and increase the robustness of PMLSM drive system, adisturbance observer for feedforward compensation is designed.Simulation results are carriedout.
