Vibration suppression with electromagnetic hybrid vibration isolators

[摘要] The design and control of a novel electromagnetic hybrid vibration isolator is presented in this paper. In the proposed hybrid vibration isolator configuration, an electromagnetic actuator and a rubber vibration isolator are configured in a parallel structure with the rubber vibration isolator installed inside the mover of the actuator. The magnetic force of the actuator is linearized by magnetic configuration design. Filtered-x least mean square (FxLMS) control algorithm is implemented for hybrid vibration isolation. Experimental results show that the vibration is suppressed significantly with the proposed hybrid vibration isolator and the FxLMS control algorithm.
