This paper proposes a cancellation control method for active machinery vibration isolation supported by multi-isolators. In this method, the cancellation signals are produced by simple independent analog circuits for each actuator, which use exciting forces that are estimated by measuring the accelerations of the actuators and the forces transmitted through the isolators. By analyzing the control equations, it can be observed that the control system is stable and causes high isolation effects for both lower order modes, where the machine vibrates as a rigid body, and higher order modes, where the natural vibrations of the machine dominate. The effectiveness of this method in wide frequency ranges is demonstrated experimentally by using a machinery model supported by four piezoelectric actuators.
