This paper presents an approach to research the active vibration isolation system under LQG control strategy through the method of co-simulation using ADAMS and MATLAB. Create System's dynamics simulation prototype in ADAMS, and return the acceleration of vibration isolation platform, the system dynamic deflection and the base's dynamic displacement as performance parameters, then establish the LQG controller of active vibration isolation system in MATLAB, and then import the prototype into MATLAB for control. The results indicate that the LQG controller can effectively improve the isolation effect of vibration isolation system, meanwhile the method of co-simulation using ADAMS and MATLAB, which can simplify the process of simulation, make the simulation results more accurate and increase the design reliability, provides a new way for dynamics studies of active vibration isolation system, or even more complex systems.
