Development of a six-axis hybrid vibration isolation system using zero-power control

This paper presents a six-axis hybrid vibration isolation system by an active zero-power control in combination with a passive weight support mechanism in order to develop a large vibration isolation table. The use of active zero-power control and weight support mechanism is the salient feature of the proposed system which enables to develop a vibration isolator with low power consumption and low cost. The system is capable to isolate as well as to control vibrations from different sources in addition to suppress large payloads or support large table. The basic characteristics of the developed system are elaborately discussed analytically. The proposed control technique can control all the motions of the system. The performance of the controller is evaluated by conducting several experiments.
