This chapter investigates the problem of robust fuzzy filter design for a class of nonlinear NCSs, which is a development of the results obtained in Chapter 6. The nonlinear plant is firstly represented by a set of local linear models based on the T-S fuzzy modeling technique presented in Chapter 7. We then proceed to the design of robust fuzzy filters for the system. By applying Lyapunov–Razumikhin method, the existence of a delay-dependent filter is given in terms of the solvability of BMIs. It should be noted that the overall designed fuzzy filter is also a blending of local linear filters according to a given fuzzy rules. The viability of the results is verified by a real world example.
