This paper studied the Stewart platform for active large-amplitude vibration control. The problem arisen from a large radio telescope in which the astronomical equipment was mounted on a platform to be stabilized by adjusting six scalable actuators, while the base platform of the mechanism itself was carried by a vibration cable-car that moves along flexible cables. The characteristics of the Stewart platform in this application are that the two platforms are coupled. The control law based on kinematics of the Stewart platform was presented. The relations between the location errors and the speed of the feed had been analyzed based on the experimental results. The control law can satisfy the requirements of FAST.
