Aimed at the flexible installation of equipments on a floor, the fixing base is modeled as a flexible base by taking account of the coupling of equipment, isolators and the base. A uniform formula of the force transmissibility of active and passive isolation is developed by transfer mobility method, and the control law of the controller is designed by the PID method, and the influence of the gains on the vibration control is discussed finally. Thereby the aim to control vibration of several modes is achieved, the effect of active isolation is marked.
