Distributed Robust Control for Linear Multiagent Systems With Intermittent Communications

This brief solves the stabilization problem of linear multiagent systems with discontinuous observations and time-varying parameter uncertainties under an undirected communication topology, where the agents can only intermittently share their information with their neighbors. Distributed observer-type protocols are constructed based on the relative states of neighboring agents and absolute states of a chosen agent. By using Lyapunov methods, some sufficient existence conditions are derived to guarantee the asymptotic stability of the multiagent systems. An algorithm is presented to properly select the coupling strength and feedback gain matrices. Finally, a simulation example is given to verify the theoretical results.
