Abstract

This work addresses the vibration control of a contactless magnetic transmission system. A learning controller is utilized in this work due to limited actuator bandwidth and uncertainties in the resonant frequencies. Performance of the controller is evaluated under self-resonance, forced oscillation, and transient response. Self-resonance is completely eliminated; while for forced oscillation, the disturbance is attenuated. Stabilization time of the transient response is also significantly reduced, thereby confirming the vibration suppression capabilities of the controller.
