N2 - This paper proposes an overall design scheme of Line-of-sight (LOS) tracking control for the integrated satellite system with vibration isolation platform (VIP) and control moment gyroscopes (CMGs). First, the three-axis attitude and motion trajectory are established for tracking the on-orbit dynamic target. To improve the accuracy and stability of target tracking, the VIP is applied to isolate CMGs micro vibration, and then controller parameters of integrated satellite system are synthetically designed based on the classical control theory. Subsequently, the effectiveness of the control scheme is verified by frequency and time domain simulation. The numerical examples show that the tracking accuracy can be increased by 80% and the stability can be improved by two orders of magnitude after adding VIP in the presence of the sample time of controller and the rotor static and dynamic imbalance.
