Paper Abstract
A design method of hybrid damping is proposed here. Values of design parameters of hybrid damping: active control gain, number and location of piezo-elements to be used to passive damping, are determined under equal vibration suppression performance condition. Vibration suppression performance is evaluated by using the gain of the accelerance transfer function of the closed loop system in modal space. According to the proposed design method, the equal vibration suppression performance with less active control power is achieved by hybrid damping. Availability of the proposed design method is experimentally demonstrated by using a flexible cantilever beam. The experimental results indicate that hybrid damping is effective comparing with fully active damping from the viewpoint of active control power under the equal vibration suppression performance condition.
