In this work, a control method to reproduce input waverorm is discussed. The acceleration waverorm of an electrohydraulic servo system is controlled by means or Linear Model Following Control (1MUC) with a timedelay reference model. This control system makes the signal transfer characteristics or forward path equivalent to that of the 2nd order Pade approximation or the timedelay characteristics. The difference signal between the output signal or the timedelay model and the output acceleration signal of the hydraulic servomotor, which is called acceleration error signal, is red back. Then, the acceleration error signal reedback makes the signal transfer characteristics or the servomotor more exact to that of the timedelay reference model. The performance or this control system is confirmed by experiments.
