Cluster Synchronization for T-S Fuzzy Complex Networks Using Pinning Control with Probabilistic Time-Varying Delays

摘要

In this article, cluster synchronization problem for Lur'e type Takagi-Sugeno (T-S) fuzzy complex networks with probabilistic time-varying delays is considered. Pinning control strategy is proposed. The probability distribution of the time-varying delay is considered. In terms of the probability distribution of the delays, a new type of system model with probability-distribution-dependent parameter matrices is proposed. Moreover, probabilistic delay is assumed to satisfy certain probability distribution and the probability of the delay takes values in some intervals. By constructing a suitable Lyapunov-Krasovskii functional involving triple integral terms and using Kronecker product with convex combination technique, some sufficient conditions are derived to ensure the cluster synchronization of designed networks such that the linear feedback controller can be used to every cluster. The problem of controller design is converted into solving a series of linear matrix inequalities. The effectiveness of our results is verified through numerical examples and simulations.
