This article investigates the mu-synchronization issues of non-dissipative coupled networks with bounded disturbances and mixed delays. By designing a hybrid non-delayed and time-delayed impulsive controller, the article provides novel sufficient conditions for achieving mu-synchronization in nonlinear complex networks. The theoretical achievements in this article are more general than previous works as the constraints on network topology and impulsive intervals are relaxed.
The mu-synchronization issues of non-dissipative coupled networks with bounded disturbances and mixed delays are studied in this article. Different from existing works, three kinds of time delays, including internal delays, coupling delays, and impulsive sampling delays, have unidentified bounds and even evolve towards infinity over time, making the concerned network more practical. Considering mu-stability theory and impulse inequality techniques, a hybrid non-delayed and time-delayed impulsive controller including both current and historical state information is designed, and several novel sufficient conditions are derived to make nonlinear complex networks achieve mu-synchronization. Moreover, not only can the constriction of dissipative coupling conditions on network topology be relaxed, but also the restriction of various time delays on impulsive intervals can be weakened, which makes the theoretical achievements in this article more general than the previous achievements. Ultimately, numerical simulations confirm the effectiveness of our results.
