Abstract�� In order to implement high accuracy space tracking-pointing task, highly stable and precise tracking-pointing mechanism with vibration control ability was designed. The mechanism adopts 6-SPS Stewart configuration. Utilizing macro-micro actuators, high accuracy pointing movement was implemented in large workspace. Combining characteristic of actuator, the control system of this mechanism was designed. The control system has tracking-pointing, vibration suppression and vibration isolation ability. Vibration isolation uses feed forward method. Tracking-pointing and vibration suppression use PID method. Utilizing MSC.ADAMS, frequency response analyze and time domain dynamic simulation of mechanism was finished. The result shows that the mechanism has higher directional precision and better vibration control ability and could implement large scale high precision tracking-pointing function in disturbance environment.
