Exponential Cluster Synchronization in Fast Switching Network Topologies: A Pinning Control Approach with Necessary and Sufficient Conditions
<|reference_start|>Exponential Cluster Synchronization in Fast Switching Network Topologies: A Pinning Control Approach with Necessary and Sufficient Conditions: This research investigates the intricate domain of synchronization problem among multiple agents operating within a dynamic fast switching network topology. We concentrate on cluster synchronization within coupled linear system under pinning control, providing both necessary and sufficient conditions. As a pivotal aspect, this paper aim to president the weakest possible conditions to make the coupled linear system realize cluster synchronization exponentially. Within the context of fast switching framework, we initially examine the necessary conditions, commencing with the transformation of the consensus problem into a stability problem, introducing a new variable to make the coupled system achieve cluster synchronization if the system is controllable; communication topology switching fast enough and the coupling strength should be sufficiently robust. Then, by using the Lyapunov theorem, we also present that the state matrix controllable is necessary for cluster synchronization. Furthermore, this paper culminating in the incorporation of contraction theory and an invariant manifold, demonstrating that the switching topology has an average is imperative for achieving cluster synchronization. Finally, we introduce three simulations to validate the efficacy of the proposed approach.<|reference_end|>
