针对麦克斯韦力驱动的快速刀具伺服(FTS)系统的轨迹跟踪问题,提出一种综合的控制方法。通过对麦克斯韦力伺服电机的系统辨识,建立系统数学模型。提出内环采用串联校正以增大系统带宽,外环采用自适应前馈抵消(AFC)控制与零相位误差跟踪控制(ZPETC)结合的控制方法。仿真结果表明,设计的控制方法对周期性的输入信号与外界干扰信号有着很好的抑制作用,实现了轨迹跟踪的精确控制,证明了该方法的有效性。
In order to solve the trajectory tracking problems of fast tool servo (FTS) system driven by Maxwell force, a com- prehensive control technique is presented. Based on the system identification of FTS, the mathematical model of system is es- tablished and the controller is designed. Series correction is used by the inner loop to improve the bandwidth. And a combi- nation of Adaptive Feedforward (AFC) controller and Zero Phase Error Tracking Controller (ZPETC) is used by the outer loop. The simulation results show that the controller has a good suppression on periodical input signals and interference sig- nals ,with the trajectory tracked precisely. The validity of this technique is proved.
