✦ Synopsis

Deadbeat control of discrete-time systems has attracted particular interest because it ensures setting the deviation response to zero within finite time and affords fast responsiveness. By using controllers which include a delay element, however, the deadbeat characteristics can be realized in the continuous-time domain, and such a tracking system has been obtained.

In this paper, we propose a new design method of continuous deadbeat control systems without using delay elements. Our new controller is composed of a digital deadbeat compensator using state feedback and a series smoothing filter. Illustrative numerical examples are presented.

The method proposed here is very simple compared with other methods and it seems to be useful for practical applications.
