摘 要:In this paper,a novel design framework is developed to solve the cooperative tracking problem of heterogeneous discrete-time multi-agent systems with unknown agent parameters and directed communication topologies.First,a distributed event-triggered observer is developed to handle the heterogeneity of the multi-agent systems.An event-triggering mechanism is proposed to reduce the amount of data transmission between neighboring agents.Then,based on the proposed observer,a discrete-time distributed model reference adaptive controller is presented to deal with the unknown parameters of the multi-agent systems.It is shown that by using the proposed observer and the model reference adaptive controller,the proposed design framework could achieve output tracking of the unknown multi-agent systems for any communication graph containing a directed spanning tree.Finally,an example is presented to illustrate the effectiveness of the proposed controller.
