Study of Whole-Satellite Active Vibration Isolation Platform

Whole-Satellite Vibration Isolation(WSVI) is an effective method to improve the dynamic environment of a satellite during the launch stage.An isolator integrated active and passive vibration control technique will have the best performance and achieve all-frequency vibration attenuation.This paper firstly reviews the latest development of WSVI technique.An active vibration isolation platform meeting the special requirement of a rocket is designed.Then several control methods suitable for the platform are investigated.Optimization of redundant actuating forces and reconfiguration of control system are analyzed.Experimental results show that the active platform achieves better low-frequency performance comparing to that of passive platform.
