In this paper, a linear-model-following control (LMFC) method using direct digital control (DDC) to reproduce the input waveform is discussed. It is difticult to control the acceleration waveform of an electrohydraulic servovibrator because of its nonlinear characteristics. To control this acceleration waveform, the LMFC method with a reference linear model of a time-delay element is introduced. This LMFC system has a state variable feedback circuit with variable feedback gains, and the calculation of the variable feedback gains is performed by means of a digital processor. The LMFC method is applied to the analogue simulation circuit and experimental apparatus to confirm reproducibility of the input signal. The experiment shows that the performance index of waveform distortion is 11 % for a reference signal of triangular waveform with a fundamental fraquency of 30 Hz.
