Abstract：Designed a third generation actuator using a type of intelligent material-piezoelectric with the functions of sensation and actuation and Improved the actuator’s ejector pin for the self-adaptive control of micro-vibration isolation platform. When it was used on the isolation system directly, the amplitude-frequency response was not very good. So we built a block mold of micro-vibration isolation platform, and the reason of non-ideal effects was analyzed. Based on that, a new type of isolation system was proposed. Through the analysis of the theory model and the experiments, the result shows that: the new method has a good isolation vibration effects, though it reduced the gain of displacement.
