基于H_∞控制理论的直线电机同步传动控制器设计

Linear motors synchrodrive controller design based on H_∞ control theory

以两台直线电机作为高速度、高精度龙门移动式镗铣床的龙门柱纵向进给的传动机构为应 用背景，基于Ｈ_∞鲁棒控制理论设计了一种同步传动控制器．其中，由ＩＰ积分－比例位置控制器满 足位置系统跟踪性能要求；由Ｈ_∞反馈控制器保证同步精度．仿真结果表明了所提出方案的合理性 和有效性．

This paper presents a H∞ controller for dual linear permanent magnet synchronous servo motors (LPMSM) synchrodrive. The H∞ control theory is used to design a feedback controller in order to guarantee synchronous precision of the system. Two IP controllers are designed so as to meet the requirment of tracking performance of position system. The results of simulation show that the controller presented is reasonable and effective.
