Abstract
This paper deals with a new design method of optimal deadbeat servo-system having L samples controlling delay. An actual deadbeat controller is composed of the series compensator with integral-action, the pre-compensator having L samples controlling delay and state feedback compensation.
The optimal deadbeat control signal which can minimize the quadratic performance index for the manipulated variable and deviation can be easily obtained from the matrix computation using sampled data of the step response of the system. Then, the deadbeat controller can be designed by using the sequence of the control signal.
Illustrative numerical examples are presented and the design method proposed here is very simple comparing with other methods, and it seems to be useful for the practical use.
