摘　　要：交叉耦合同步控制是多电机同步控制的一种主要形式,但当系统中一台电机存在外界干扰时,交叉耦合部分会将干扰作用传递到其他电机伺服系统,对各电机伺服精度和同步精度均会产生不良影响。针对该问题,设计了双永磁同步直线电机同步控制系统,在双电机同步控制系统中加入线性扩张状态观测器。仿真及实验结果均证明,扩张状态观测器在双电机交叉耦合同步控制系统中能够有效提高各电机位置伺服精度和同步控制精度。Cross coupling synchronous control is mainly applied to the synchronous control for multi motor. when the motor is disturbed in external environment, the interference is transfered to other motor servo systems by the cross coupling part, which can result in adverse effects on the servo precision and synchronization accuracy of each motor. For this, the synchronous control system for the dual permanent magnet synchronous linear motor is designed, and the linear extended state observer is applied to the synchronous control system of the dual motors. The result of the simulation test shows that the extended state observer can be used to effectively improve the position servo precision and the synchronization control precision in the dual motor cross coupling synchronous control system.
