研究了基于输出耦合的异构时滞离散多智能体系统的输出同步问题。首先，给出了用描述符动力学建模的个体智能体的耗散性的充分条件。提出了基于相邻智能体输出的全分布式共识协议，表明个体耗散导致整个多智能体系统的输出同步。该同步方案对范数有界不确定性具有较强的鲁棒性。此外，还研究了具有事件触发机制的多智能体系统基于耗散度的协作结果的对应关系。所提出的触发机制和共识协议解决了所有允许的不确定性和时变延迟的同步问题。最后，进行了一个非均匀的数值模型来说明所提出策略的有效性。
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.
