Abstract

In this paper we propose a design method of an optimal deadbeat control system in consideration of the response between the sampling instant.<br>The sequence of the deadbeat control signal which minimizes the quadratic performance index for the manipulated variable and deviation can be easily obtained from the matrix computation by 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.<br>We also studied the result of a computer simulation by the present method and apply the method to a speed control system of the inverter-fed induction motor to show the control effect, and it seems to be useful for the practical application.
