Robust H∞ control for uncertain fuzzy neutral systems with both distributed delays and input delays

Abstract

This paper further investigated the problem of robust H∞ control for uncertain fuzzy neutral systems with both distributed delays and input delays. Different from literature[4], not only input delays will be carefully considered, but also how to to reducing the conservativeness in the designing of fuzzy controller will be shown by Relaxed LMI. Based on Takagi-Sugeno (T-S) fuzzy model and a useful matrix inequality, some sufficient conditions for the solvability of the problem is obtained by utilizing a proper Lyapunov functional and LMI approach.
