Abstract

This literature mainly concerns finite-time bipartite synchronization (FTBS) of networked systems (NSs) with time-varying and random coupling delays based on signed graphs. Via Bernoulli random variables, NSs will switch between the delayed coupled systems and coupled systems without time delays. Two kinds of quantized controllers are constructed to realize the goal of synchronization. Different from many existing finite-time stability results established by the classical finite-time stability theorem, the results of this paper are obtained directly based on 1-norm analytical method. Numerical examples are employed to verify the presented results.
