Active vibration control simulation of the vibration isolation platform

The active vibration isolation platform (AVIP) is given with four modules, each of which consists of two magnetostrictive actuators, one is in horizontal direction and the other is in vertical, and four spring-rubber elements for passive support and damper. The method to control six degree-of-freedom (DOF) vibration of the AVIP with eight actuators is presented. This paper addresses the dynamics model of the AVIP. And then based on the model built already, the active vibration control simulation (AVCS) of the AVIP has been executed with the adaptive filter algorithm. By the numerical simulations, it is shown that the proposed method of simulation is efficient and active multiple DOF vibration control of the AVIP is feasible.
