Abstract：In order to isolate the vibration for precision instruments, a new smart composite structure is presented in this paper, which is consisting of the PVDF piezoelectric film actuator and sensor. The deformation formula of the multilayer PVDF piezoelectric film actuator along the thickness direction is derived according to piezoelectric equation and the vibration isolation theoretical model of this new smart composite structure is established in detail. By using LMS adaptive control algorithm, vibration isolation dynamic characteristics of the new smart composite structure are simulated with the software of Matlab and ANSYS. The simulation results of ANSYS are in good agreement with those of Matlab， which verifies the validity of the new smart composite structure. This investigation will provide an important theoretical foundation for the micro-displacement active vibration isolation of precision instruments and micro-nano equipment.
