Further study on robust H∞ control for uncertain fuzzy neutral systems with distributed delays

This paper further investigates the problems of robust H∞ control for uncertain Takagi-Sugeno (T-S) fuzzy neutral systems with distributed time delays. The purpose is to design state feedback fuzzy controllers such that the resulting closed-loop system is robustly stable with an H∞ performance level. Two Sufficient conditions for the solvability of the problem are obtained by utilizing a Lyapunov functional together with the relaxed linear matrix inequality (LMI) approach. A numerical example is provided to demonstrate the applicability of the two proposed design method and difference between them are also discussed.
