Abstract
A new control design framework for vibration control, the hybrid control of active and semi-active control, is proposed in the paper. In the hybrid control framework, structural systems having both of an actuator for active vibration control and a semi-active control device, e.g., MR damper etc., is defined as the control object. In the proposed control approach, the higher control performance is aimed with the hybrid manner between the actuator and the semi-active control device. A design method to determine the active control law and the command signal of the semi-active control device based on the one-step prediction of the control output is proposed. A design example of the vibration control for a base-isolated building is presented to show the effectiveness of the proposed control framework.
