Improved stability condition for fuzzy systems with interval time varying delay

In this paper, a new and improved stability condition is proposed for Takagi-Sugeno (T-S) fuzzy systems subject to interval time varying delay. The stability analysis is carried out by constructing a new Lyapunov-Krasovskii (L-K) functional along with the use of tighter bounding integral inequality to approximate the integral term coming out from the derivative of L-K functional. Two numerical examples are included to show the effectiveness of the proposed theoretical results over some existing approaches.
