Digital redesign of continuous control system via fuzzy logic control

The goal of the digitally redesigned control systems is to achieve the performance of their original continuous systems even when using a very low sampling rate. This paper presents a digital redesign method based on a fuzzy logic approach which achieves this goal. The method utilizes the block pulse function in order to approximate the continuous control at every sampling interval for the fuzzy logic controller´s data. Simulation results show that the digitally redesigned control system based on fuzzy logic control gives quite satisfactory responses
