H∞ Sample-Data Control of Fuzzy Systems with Input Delay

Abstract

This paper is concerned with H∞ sampled-data control for uncertain fuzzy systems. A new approach to sampled-data control is introduced. The system is modelled as a continuous-time fuzzy system, while in practice, the control input has a piecewise-continuous delay. Sufficient conditions for the closed-loop system with a sampled-data state feedback controller to achieve a prescribed H∞ state feedback control for fuzzy systems. We also propose a design method of sampled-data state feedback controller for uncertain fuzzy systems. Numerical examples are given to illustrate our sampled-data state feedback control.
