摘　　要：在多智能体信息交互过程中,由于通信带宽有限,需要减少资源消耗。对此,提出了一种基于通信链路感知的动态事件触发控制方案。考虑到触发条件中信道容量的影响,设计了链路感知的一致性触发机制。该机制的触发频率可随通信资源的变化而智能调节。在通信网络带宽状态一般时,降低触发频率可减少网络中的通信量;在通信网络带宽性能较好时,增加触发频率可加快系统的收敛速度。此外,为增加系统的可扩展性,引入了具有有限稳定耦合增益的自适应控制协议,使得控制策略不需要使用网络拓扑相关的全局信息。基于稳定性定理对多智能体系统的一致性进行了推导,并通过正下界法证明了系统不存在Zeno行为。仿真结果表明,所提的通信链路感知动态事件触发机制可在通信资源和收敛速度之间起到调节作用,有效提升系统网络带宽的利用率。In the process of multi-agent information interaction,the communication bandwidth is limited and resource consumption needs to be reduced.In this regard,a dynamic event triggered control scheme based on communication link awareness is proposed.Considering the impact of channel capacity in triggered conditions,a link-aware consensus triggered mechanism is designed.This mechanism's triggered frequency can intelligently adjust to changes in communication resources.When the bandwidth status of the communication network is moderate,reducing the triggered frequency can decrease the communication traffic within the network.Conversely,when the bandwidth performance of the communication network is good,increasing the triggered frequency can accelerate the system's convergence speed.Additionally,to enhance the system's scalability,an adaptive control protocol with finite stable coupling gains is introduced,eliminating the need for global information related to network topology in the control strategy.The consensus of multi-agent systems is derived based on stability theorems,and the absence of Zeno behavior in the system is proven by using the lower bound method.Simulation results demonstrate that the proposed communication link-aware dynamic event triggered mechanism can effectively regulate between communication resources and convergence speed,making it more suitable for scenarios where agents rely on wireless communication transmission models.
