The research on the active vibration isolator

Abstract

Abstract:The effect on the high-precision imaging load because of the vibrations from the satellite platforms is becoming more and more non negligible. In the paper, the bi-layer structure mixed with passive part and active part is adopted for the leg and the location of the actuator is studied. As for the control algorithm, the loop-shaping approach is introduced. Additionally, the cross-coupling control strategy is adopted to improve the vibration isolation performance for the vibration isolator with two legs.
