Abstract: Quantized consensus of second-order multi-agent systems with event-triggered control is investigated to deal with the problem, whose information needed to be quantified in the process of network communication. The consensus protocol based on the event-triggered control strategy is proposed, and the logarithmic quantizer is used to quantify control input. By using Lyapunov stability theory, some sufficient conditions on the consensus of the multi-agent systems are obtained. A numerical simulation is provided to demonstrate the effectiveness of the proposed theoretical results.

摘要： 针对多智能体系统网络通信过程中信息需要量化的情况，研究了二阶多智能体系统在事件触发控制下的量化一致性。基于事件触发控制策略，提出一致性协议，并采用对数量化器对控制输入进行量化处理。利用Lyapunov稳定性理论，对系统进行一致性分析，得到了多智能体系统渐近趋于一致的充分条件。仿真结果说明了理论分析的有效性。
