Practical Finite-Time Synchronization of T-S Fuzzy Complex Networks with Different Couplings via Semi-intermittent Control

Based on Takagi-Sugeno(T-S) fuzzy models, this paper investigates practical finite-time(PFET) synchronization of complex networks with a linear coupling and two different kinds of nonlinear couplings, including nonlinear relative state coupling and nonlinear absolute state coupling. A new stability lemma is established based on different time intervals. Two kinds of controllers are designed including semi-intermittent state feedback control and semi-intermittent adaptive control. As a result, with the help of new stability lemma and control schemes, the goal of PFET synchronization is realized via Lyapunov functionals. Eventually, simulation experiments are presented to verify our new results.
