This paper investigates output synchronization of heterogenous time-delay discrete-time multiagent systems via output couplings. Firstly, sufficient conditions are provided to guarantee dissipativity for an individual agent modeled by the descriptor dynamics. Fully distributed consensus protocol based on the outputs of the neighboring agents is proposed to show that the individual dissipativity leads to output synchronization of the overall multiagent system. The proposed synchronization scheme exhibits a strong robustness facing norm-bounded uncertainties. Moreover, the counterparts of the result of the cooperation based on dissipativity for the multiagent system with event triggering mechanism is also investigated. The proposed triggering mechanism and the consensus protocol solve the synchronization for all admissible uncertainties and time varying delay. Finally, a numerical heterogeneous model is carried out to illustrate the effectiveness of the proposed strategies.

离散多主体系统的输出同步：一种协作事件触发的耗散方法

本文通过输出耦合研究了异构时滞离散时间多主体系统的输出同步。首先，提供足够的条件来保证由描述符动力学建模的单个代理的耗散性。提出了一种基于相邻代理输出的完全分布式共识协议，以表明个体的耗散性导致整个多代理系统的输出同步。所提出的同步方案表现出强大的鲁棒性，面临规范界的不确定性。此外，还研究了基于耗散性的具有事件触发机制的多主体系统的合作结果。所提出的触发机制和共识协议解决了所有可容许的不确定性和时变延迟的同步问题。最后，建立了一个数值异构模型来说明所提出策略的有效性。
