Abstract：To 6-DOF active-passive vibration isolation platform, the key technologies have been studied, which include the experimental modeling and the controller design. According to the input and output data of the modeling experiment, the nominal parameters of the system are identified with the recurrence least squares algorithm (RLS). Taking into account the uncertainties from experimental modeling and vibration control purposes, the robust controller has been designed through the application of mixed sensitivity H∞-based. Final vibration isolation experimental results show that active-passive vibration isolation platform, can not only effectively isolate the interference of the foundation, but also better restrain the force directly on the platform.
