VIBRATION CONTROL APPARATUS

A vibration control apparatus detects a physical value influencing characteristics of a suspension supporting a vibrating body and a state value representing movement of the suspension, calculates an optimal target control force in consideration of an external force or disturbance acting on the suspension on the basis of the physical and state values as outputs from a state detecting system, calculates the detection control force corresponding to the detected physical value, and continuously variably controls the suspension characteristics so as to generate a control force corresponding to the difference between the target and detection control forces in consideration of the external force or disturbance acting on the suspension, whereby vibrations are prevented by equivalently applying the target control force on the suspension.
