A feedback-feedforward control algorithm which utilizes information on future input is presented. When input accelerations can be considered as the output of a vibration system, the input accelerations are determined by the past and future input time-histories of the vibration system. This means that we can regard the former component as the part of information on future input time-histories. In this case, we can propose a new method of feedback-feedforward control algorithm. Numerical calculations are done to demonstrate effectiveness of the method. It becomes clear that the proposed method has higher control efficiency than the velocity feedback control.
