Abstract

Experiment modeling is an effective means to find out the essence of physical phenomenon. To 6-DOF active-passive vibration isolation platform, experiment modeling is the premise to make vibration isolation be active-controlled and also the key to gain satisfying control result. Conditions of sensors’ arrangement are presented by deriving the coordinate change from physical space to sensor space. Combining with the transcendental thesis of 6-DOF active-passive vibration isolation platform and the signal obtained from tests, the dynamic model of actuator-sensor is build up using least square estimation recurrence algorithm.
