摘要: 针对双驱运动平台同步误差导致的定位精度下降、摩擦扰动增大等问题,提出一种双电机跟踪误差自适应补偿的双驱运动平台同步控制方法。先对双驱运动平台进行系统建模并分析同步误差导致的摩擦扰动力。其次,构建双驱运动平台自适应同步控制架构,提出面向弱跟踪性能电机的实时同步误差选择性补偿策略,设计融合单轴位置指令跟踪和同步位置误差补偿的同步位置控制器,为速度环提供兼顾单轴跟踪精度和双轴同步性能的速度控制指令。最后,完成双驱运动平台的同步控制仿真和试验:在位置环和速度环采用了比例积分微分(Proportion integration differentiation,PID)控制算法,对比多种同步控制策略的控制性能。仿真与试验结果表明,自适应同步控制策略明显优于并行同步控制策略。与交叉耦合控制策略相比,该自适应的控制策略不仅显著提升了单电机的位置跟踪精度,还增强了双电机的位置同步性能。

Abstract: The synchronization error of a dual-drive motion platform leads to decreased positioning accuracy and increased frictional perturbation. To address these problems, a synchronous control method based on adaptive compensation of dual-motor tracking error is proposed for the dual-drive motion platform. Firstly, the models of linear motors are systematically established and the friction perturbation force caused by the synchronization error is analyzed. Then, an adaptive synchronous control architecture is constructed for the dual-drive motion platform. A selective compensation strategy of real-time synchronous error is proposed for the motor with weak tracking performance. Moreover, a synchronous position controller is devised by combining single-axis position command tracking and synchronous position error compensation. This controller is used to provide the speed control command while both the single-axis tracking accuracy and dual-axis synchronous performance are considered. Finally, the synchronous control simulation and experiment are conducted on a dual-drive motion platform. PID control algorithm is implemented in the loops of position control and speed control, respectively, and the control performances of several synchronous control strategies are compared. The results of simulation and experiment show that the proposed adaptive synchronous control strategy obviously outperforms the parallel synchronous control strategy. Compared with the cross-coupling control strategy, this designed control strategy can not only improve the position tracking accuracy of each motor remarkably, but also enhance the position synchronization performance of dual motors.
