摘要
将零相位跟踪控制(ZPETC)和扰动观测器(DOB)结合,给出了适合高性能数控机床进给运动的零相位跟踪鲁棒控制方法,并讨论了该控制算法的特点。仿真结果证明算法是可行和有效的。
This paper combines zero phase error tacking controller and disturbance observer and proposes the robust designing method suitable for high performance CNC system. Further, features associated with the controller is discussed. Finally, simulation results show that the approach has the potential to improve the tacking performance.
