The research work had been done on the control channel mathematic model of piezoelectric actuator using LMS adaptive algorithm. The control channel mathematic model of piezoelectric actuator is a necessary condition to develop many kinds of active isolation or vibration control system based on FX-LMS control algorithm. First, the detailed theory analysis had been derived on the LMS algorithm, and the realized process had been analyzed. Then based on it, the control channel mathematic model identification system had been developed using LMS algorithm. At last, it was used to identify some control channel mathematic model of one dimension micro vibration active isolation platform using piezoelectric stack actuator in order to test the feasibility and efficiency of the identification system we developed. The result includes that the identified control channel mathematic model can be used to develop control system based LMS adaptive algorithm.
