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. © 1999 Scripta Technica, Electr Eng Jpn, 127(2): 42–48, 1999
