Abstract

This paper presents a scaling and squaring geometric-series approximation method for digital redesign of a well-designed continuous-time state-feedback controller. For a relatively longer sampling period, the states of digitally controlled sampled-data system closely match those of the original continuous-time controlled system by using the proposed digitally redesigned controller. The developed static digital controller can be implemented easily by applying economical and dependable digital electronics. A numerical example is given not only to compare the proposed method with some existing methods but also to demonstrate the effectiveness of the proposed method.
