Average-consensus filter problem is investigated for a mixed-order multi-agent system, which consists of first-order and second-order agents, and the proportional-integral consensus filter algorithms are proposed for the agents with different constant inputs. Based on generalized Nyquist stability criterion, sufficient convergence conditions are obtained for the multiagent system under a fixed, symmetric...
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...
Usual consensus algorithm is adopted to solve the consensus problem of general linear first-order multi-agent systems subjected to communication delay. In addition to normal synchronously-coupled form and asynchronously-coupled form, we proposed a new compensation-based form for the consensus algorithm. With the help of frequency-domain analysis, consensus conditions are obtained for the agents to...
For the multi-agent systems with agent's dynamics described by high-order integrator, and usual consensus algorithm composed of the states' coordination control parts is proposed. Under communication delay, consensus algorithm in asynchronously-coupled form just can make the agents achieve a stationary consensus, and sufficient consensus condition is obtained based on frequency-domain analysis. To...
