Deadbeat Control of Discrete-Time Systems Considered the Transient Response

Abstract

Deadbeat control of the linear discrete-time systems has the specific feature that the error is settled to zero in the finite number of control steps. But on the other hand, a deadbeat control system has an excessive overshoot in the input and/or output transient response for some control objective. Such transient characteristics are not desirable in the practical use of the deadbeat control.
In this paper, we study the design of deadbeat control system which is optimally tuned the transient responses. A pre-compensator is introduced and designed to minimize the quadratic form of the input and output errors. A numerical example is given to show how well the transient responses of deadbeat control system are improved.
