In this work, the vibration control performance of an active mount using an electromagnetic actuator is experimentally evaluated. After manufacturing an electromagnetic actuator, dynamic characteristics such as the actuating force and response time of the electromagnetic actuator are experimentally investigated. The material properties of the rubber element are also experimentally identified. An active mount system using an electromagnetic actuator and a rubber element is designed and the governing equation is derived. A sliding mode controller that has inherent robustness to external disturbance is designed and implemented in the system. Vibration control performances of the active mount system, such as acceleration and transmitted force, are experimentally evaluated and they are presented in both time and frequency domains. It is observed that the structural vibration is effectively attenuated by applying proper control input to the electromagnetic actuator.
