Exploration of magnetic suspension technology used for spacecraft micro-vibration isolation

Spacecraft micro-vibration is still an important issue that influences space remote-sensing resolution and satellite laser communication pointing precision. As its favorable low frequency oscillation suppression performance, active vibration control becomes a main research direction in the micro-vibration abatement. This paper adopts magnetic suspension vibration isolation control method to construct a 6-DOFs Stewart platform with 6 single DOF magnetic suspension actuators, which is used for isolating the micro-vibration generated by 4 single gimbal control moment gyroscopes(SGCMGs) disturbances. Then an integrated model including satellite platform, SGCMGs and magnetic suspension Stewart platform was developed. Finally, a comprehensive simulation proceeded to illustrate the availability of the magnetic suspension vibration isolation strategy.
