This paper proposes a design method of an optimal deadbeat control system that takes into account the response between the sampling instant. The sequence of the deadbeat control signal that minimizes the quadratic performance index for the manipulated variable and deviation can be obtained easily from the matrix computation using the step response of the system. Then, the series compensation controller and series integral + local feedback compensation controller with fictitious sampler can be designed by using sequence of the control signal. The results of a computer simulation by the present method and application of this method to a speed control system of the inverter‐fed induction motor have been studied in order to explore the control effect. The method seems to be useful for practical application. © 1997 Scripta Technica, Inc. Electr Eng Jpn, 118 (1): 83–92, 1997
