This paper deals with a class of T-S fuzzy models with time delays and uncertainties. On the basis of the socalled delay partitioning idea and a novel Lyapunov function candidate, a time-delay-dependent approach is provided in order to alleviate the conservatism of conditions for system stability. At the same time, the sliding-mode and adaptive control techniques are adopted to deal with the uncertainties, trying to remove some drawbacks in the existing results of fuzzy sliding-mode control systems.
