This paper addresses the consensus problem of multiagent systems with a time-invariant communication topology consisting general linear node dynamics. A distributed observer-type protocol based on relative output measurements is proposed. new framework introduced to address in unified way and synchronization complex networks. Under this framework, having spanning tree can be cast into stability set matrices same low dimension. The notion region then analyzed. It shown that there exists an...
This paper addresses the distributed consensus protocol design problem for multi-agent systems with general linear dynamics and directed communication graphs. Existing works usually protocols using smallest real part of nonzero eigenvalues Laplacian matrix associated graph, which however is global information. In this paper, based on only agent relative states neighboring agents, a adaptive designed to achieve leader-follower any graph containing spanning tree leader as root node. The...

Distributed relative-state protocols an adaptive law adjusting coupling weights between neighboring agents are designed both cases, under which is reached all undirected connected communication graphs. Extensions to case a leader-follower graph further studied. In contrast existing results in literature, here can be implemented by each agent fully fashion...
This technical note considers the distributed tracking control problem of multiagent systems with general linear dynamics and a leader whose input is nonzero not available to any follower. Based on relative states neighboring agents, two discontinuous controllers with, respectively, static adaptive coupling gains, are designed for each follower ensure that followers converge state leader, if interaction graph among undirected, has directed paths all followers, leader's bounded. A sufficient...
SUMMARY This paper considers the containment control problems for both continuous‐time and discrete‐time multi‐agent systems with general linear dynamics under directed communication topologies. Distributed dynamic controllers based on relative outputs of neighboring agents are constructed cases, which states followers will asymptotically converge to convex hull formed by those leaders if, each follower, there exists at least one leader that has a path follower. Sufficient conditions...
This paper considers the distributed event-triggered consensus problem for general linear multiagent networks. Both leaderless and leader-follower problems are considered. Based on local sampled state information, adaptive protocols designed, which can ensure that of agents is achieved, Zeno behavior excluded by showing interval between any two triggering events lower-bounded a strictly positive value. Compared with previous related works, our main contribution proposed event-based fully...
Nuclear factor kappaB (NF-kappaB) and activator protein 1 (AP-1) transcription factors regulate many important biological pathological processes. Activation of NF-kappaB is regulated by the inducible phosphorylation inhibitor IkappaB kinase. In contrast, Fos, a key component AP-1, primarily transcriptionally serum responsive (SRFs) ternary complex (TCFs). Despite these different regulatory mechanisms, there an intriguing possibility that AP-1 may modulate each other, thus expanding scope two...
This note considers the distributed optimization problem on directed graphs with nonconvex local objective functions and unknown network connectivity. A new adaptive algorithm is proposed to minimize a differentiable global function. By introducing dynamic coupling gains updating using relative information of system states, nonconvexity functions, connectivity, uncertain dynamics caused by locally Lipschitz gradients are tackled concurrently. Consequently, asymptotic convergence established...

Summary This paper considers the containment control problem for multi‐agent systems with general linear dynamics and multiple leaders whose inputs are possibly nonzero time varying. Based on relative states of neighboring agents, a distributed static continuous controller is designed, under which error uniformly ultimately bounded upper bound can be made arbitrarily small, if subgraph associated followers undirected and, each follower, there exists at least one leader that has directed path...
This paper is concerned with the distributed consensus tracking problem of uncertain multiagent systems directed communication topology and a single high-dimensional leader. Compared existing related works, dynamics each follower in present framework are subject to unmodeled unknown external disturbances, which more practical various applications. Furthermore, dimensions leader's may be different those followers' dynamics. Under mild assumption that can directly or indirectly sense output...

Abstract This article addresses the consensus problem for cooperative multiple agents with nonlinear dynamics on a fixed directed information network, where each agent can only communicate its neighbours intermittently. A class of control algorithms is first introduced, using intermittent relative local information. By combining tools from switching systems and Lyapunov stability theory, some sufficient conditions are established multi-agent without any external disturbances under strongly...
This paper studies the distributed event-triggered tracking control problem of general linear multiagent systems with a dynamic leader, whose input might be nonzero and unknown. The existence leader's unknown renders network heterogeneous largely increases difficulty designing event-based protocols. To solve this problem, we establish novel asynchronous edge-based mechanism, under which communication is not required from leader to its out-neighbors (informed followers) or by edge, unless...
