Deadbeat control of the discrete-time systems has the specific feature that the error is settled to zero in the finite control step. But in the practical system, there exist input saturation on the control signal, and undesirable effect such as reset wind-up may be occured.
In this paper, a new design method of deadbeat control system is proposed for the plants with input saturation, and apply it to a speed control of the current type inverter induction motor. The deadbeat control signal which considers saturation limitations can be easily obtained by matrix computation. Then, the deadbeat controller not only for the series integral action but also state feedback compensation can be design by using the sequence of the control signal.
Illustrative numerical example are presented, and it is found from experimental results that the method proposed here seems to be useful for the practical system.
