%X This paper is concerned with the problem of delay dependent robust stability and observer based robust control of a class of time delay uncertain systems with nonlinear perturbations. The robustly stable or exponentially stable sufficient conditions which depend on the size of delay of systems are discussed for open loop systems by using linear matrix inequality(LMI) incorporated with algebraic value inequality(AVI) approach. Furthermore, we design the state observer of the system and obtain delay dependent controllable sufficient conditions.
