Group consensus problem is investigated for the second-order multi-agent systems with communication delay under general directed topology, and stationary consensus protocols are proposed for two sub-groups. By using algebraic graph theory and matrix theory, consensus conditions are obtained for second-order multi-agent systems without time delay firstly. Based on frequency-domain analysis method,...
Event-triggered consensus problem is studied for a class of heterogeneous first-order multi-agent system, which contains multiple single integrators with different nominal velocities, and an adaptive consensus algorithm in the leader-following structure is adopted. Under the event-triggered mechanism, the agents’ inputs are only updated at discrete times determined by a centralized event-triggered...
Scaled group consensus problem of second-order multi-agent systems is investigated in this paper, and the dynamical and stationary consensus protocols are proposed respectively. Firstly, scaled group consensus is analyzed for the second-order multi-agent systems with directed interconnection topology. Subjected to time-varying communication delay, then, the dynamical and stationary consensus protocols...
This paper investigates the coupled-group consensus problem of second-order multi-agent systems subjected to communication delay, and we adopt a linear synchronously-coupled consensus protocol under the assumption that the sum of each agent's adjacent weights to the agents in the other sub-group is zero in the interconnection topology. Based on Lyapunov-Krasovskii functional, delay-dependent sufficient...
