New Digital Redesign Method in use of N-Delay Control.

Abstract

A new digital redesign method is proposed for both a continuous time state feedback controller and a dynamic controller. In the proposed method, the N-Delay control is employed, and the lth plant inputs are changed Nl times during one sampling period. The goal of this paper is to develop a new digital controller from the analog controller so that the states of the digitally controlled closed-loop system completely match those of the original continuous time controlled closed-loop system at every sampling period. An illustrative example of position control using DC servo motor is presented.
