Abstract

In this paper, a position control of a linear slider with twin linear drives is considered. Recently, for the high-speed response, several linear motors are used for the linear slider system . In such a linear slider, if the linear drives are controlled individually, these position responses possibly vibrate by interaction of output of the motors. For the method to control this vibration, this paper shows the dynamic model of the linear slider system which consists of the decoupled two motion systems by coordinate transformation, and proposes a feedback controller which is designed for these two decoupled systems. Effectiveness of the proposed method is confirmed by experiments.
