摘　　要：以龙门移动式数控机床的双轴同步传动机构为背景,研究两套永磁直线同步电动机(PMLSM)伺服系统在具有一定动态指标和抗干扰性能前提下的同步控制问题。针对两套进给系统难以同步且易受干扰的特点,设计了一种基于模糊控制的交叉耦合补偿控制器。同时为了提高每套伺服系统的跟踪和抗扰能力,设计了最优预见前馈补偿。仿真结果表明该系统对不平衡负载具有良好的同步抗扰性能。The synchronous control of the permanent magnet linear synchronous motors servo systems with some dynamic targets and anti-interference performance was studied for the dual axes synchronous-drive mechanism of gantry-moving type NC machine tool. A cross coupling compensator was designed based on fuzzy control to overcome the problem of hard synchronization and easily being disturbed of the two feed systems. For improving tracking performance and anti-interference ability of each servo system, the method of optimal preview feedforward compensation was presented. The simulation results verify that this system has good synchronous performance and anti-interference ability.
