Model and simulation for two-axis vibration isolator

The satellite platform in the orbit, as the payload carrier, always suffers from the complex spatial dynamics disturbances. The disturbances affect the LOS stabilization of the high resolution optical payload and then affect the quality of the image from the high resolution earth observation system. In order to solve the problem, the vibration isolation technique-placing the appropriate vibration isolators between the vibration source and system to isolate the direct transmission of the vibration is adopted. In the paper, we take the two-axis isolator as the object of study, build its dynamic model and design the controller for the two-axis isolator. We use ADAMS which is used for the mechanical dynamics and MATLAB to do the combined simulation to verify the controller's effects.
