Speed and position control of the AC motor using variable structure controller with disturbance observer
외란 관측자와 가변구조제어기를 이용한 AC 서보모터의 속도 및 위치 제어
Abstract
This paper develops an AC motor controller for applications. The AC motor controller is designed based on the variable structure control method and a variable structure disturbance observer is added to reduce the effects of exogenous disturbances. The designed controller is installed on the z-axis of a CNC machining center and milling experiments were performed. The results show improved performance on both position and speed tracking, when compared to the factory-designed servo controller.
