Synchronization of Nonlinearly and Stochastically Coupled Markovian Switching Networks via Event-triggered Sampling

Abstract 

In this talk, we consider the exponential synchronization problem for a new array of nonlinearly and stochastically coupled networks via events-triggered sampling (ETS) by self adaptive learning. The networks include the following features: (1) a Bernoulli stochastic variable is introduced to describe the random structural coupling; (2) a stochastic variable with positive mean is used to model the coupling strength; (3) a continuous time homogeneous Markov chain is employed to characterize the dynamical switching of the coupling structure and pinned node sets. The proposed network model is capable to capture various stochastic effect of external environment during the network operations. In order to reduce networks’ workload, different ETS strategies for network self-adaptive learning are proposed under continuous and discrete monitoring respectively. Based on these ETS approaches, several suffificient conditions for synchronization are derived by employing stochastic Lyapunov Krasovskii functions, the properties of stochastic processes, and some linear matrix inequalities.
