Fuzzy control for continuous time-varying delay systems

In this paper, the problem of stability analysis and fuzzy controller design is investigated for continuous-time systems with time-varying delays. Based on the reciprocally convex technique, a sufficient condition of the asymptotic stability is developed for the concerned fuzzy delayed systems. Then, from the derived results, a novel state feedback fuzzy controller is designed. Finally, the parameters of the proposed controller are derived in terms of linear matrix inequalities, which can be easily figure out by the optimization techniques.
