State Feedback Control for Uncertain Nonlinear Networked Control Systems

Introduction

In this chapter, our concern is to consider a class of nonlinear uncertain NCSs with sensors and actuators connected to a controller via two communication networks in the continuous-time domain. Linear feedback control techniques can be utilized as in the case of feedback stabilization. The design procedure is stated as follows. First the nonlinear plant is represented by a T-S fuzzy model. In this type of fuzzy model, local dynamics in different state space regions are represented by linear models. The overall model of the system is achieved by “blending” of these linear models. Then for each local linear model, a linear feedback controller is to be designed. The resulting overall controller, which is nonlinear in general, is again a fuzzy blending of each individual linear controller.
