Stationary consensus of heterogeneous multi-agent systems with bounded communication delays

摘要

Consensus seeking is investigated for the discrete-time heterogeneous multi-agent systems composed of first-order agents and second-order agents, and two stationary consensus algorithms are constructed for the first-order agents and the second-order agents, respectively. Based on the properties of nonnegative matrices, sufficient consensus criteria are obtained for the agents with bounded communication delays under fixed topology and switching topologies, respectively. With some prerequisites on the coupling weights and the sampling interval, the asymptotic consensus achievement of the dynamic agents is independent of the communication delay, but strictly depends on the connectedness of the interconnection topology. Simulation results illustrate the correctness of the results.
