SUMMARYIn this paper, position control of a linear slider with twin linear drives is considered. Recently, for high-speed response, several linear motors have been used for linear slider systems.In such a linear slider, if the linear drives are controlled individually, their position responses may undergo vibrational disturbance by interaction with the output of the motors. To control this vibration, this paper presents a dynamic model of a linear slider system which consists of two motion systems decoupled by coordinate transformation, and proposes a feedback controller which is designed for these two decoupled systems. The effectiveness of the proposed method is confirmed by experiments.
