We consider almost regulated output synchronization for directed heterogeneous networks where agents are nonlinear and non-introspective (i.e. agents have no access to their own states or outputs) in the presence of external disturbances. A purely decentralized time-invariant protocol based on a low-and-high gain method is designed for each agent to achieve almost regulated output synchronization...
We consider two synchronization problems, namely, state synchronization for networks of identical linear agents, and regulated output synchronization for networks of non-identical linear agents, under a time-varying topology. Agents are assumed to be multiple-input multiple-output (MIMO), minimum-phase, right invertible and non-introspective (i.e., they only receive relative output information from...
We consider the synchronization problem for homogeneous networks of nonlinear SISO agents connected via diffusive partial-state coupling. The agents are non-introspective (i.e., they do not have access to their own state or output), and thus unable to manipulate their own dynamics in order to present themselves differently to the network. Moreover, the agents are not allowed to exchange additional...
We introduce the notions of “ℌ∞ almost regulated synchronization” and “ℌ∞ almost formation” for multi-agent systems subject to external disturbances and under directed interconnection structures. We assume that agents are linear, right-invertible and introspective with non-identical dynamics. The objective is to suppress the impact of disturbances on the synchronization error dynamics in terms of...
This paper studies the consensus among identical agents that are at most critically unstable and coupled through networks with uniform constant communication delay. An achievable upper bound of delay tolerance is obtained which explicitly depends on agent dynamics and network topology. The dependence on network topology disappears in the case of undirected networks. For any delay satisfying this upper...
In this paper, we consider three problems, namely, the output consensus problem, the model-reference output consensus problem, and the regulation of output consensus problem, for a network of non-identical right-invertible linear agents. The network provides each agent with a linear combination of multiple agents' outputs. We assume that all the agents are introspective, meaning that they have access...
