Networked H_? Tracking Control For Polynomial Fuzzy-Model-Based Systems With A Adaptive Event-triggered Communication Scheme

This paper investigates the problem of networked H? tracking control for polyno-mial fuzzy-model-based systems. First, in order to reduce the unnecessary waste of the limited network bandwidth resources, a adaptive event-triggered communication scheme is proposed. On this basis, a networked tracking control model of polynomial fuzzy mod-el systems is established. Next, taking the deviation bounds of asynchronous normal-ized membership functions into account, based on the Lyapunov stability theory, sum-of-squares(SOS)approach and convex combination technique , several sufficient criterias ensuring the augmented system asymptotically stable with the prescribed H? tracking performance are obtained. Based on this performance criterion, some criterias on the ex-istence of the fuzzy tracking controller are established. Finally, an illustrative example is given to show the effectiveness of the proposed method.
