中文摘要： 多智能体系统一致性问题在民用和军用领域都有着广泛的应用，但由于缺乏监控所有智能体活动的中心实体，多智能体系统容易遭受外部的恶意攻击，导致系统性能的衰减，因此研究多智能体系统一致性的安全性问题有着重要的意义。本项目针对拜占庭故障下含多通信时滞和测量噪声的网络化多智能体系统，拟开展以下研究内容：（1）建立融多通信时滞、测量噪声及并发智能体拜占庭故障的多智能体系统一致性模型；（2）分析系统是否实现一致性与合法性，寻找系统实现一致性与合法性的条件；（3）设计新的鲁棒一致性协议，降低抗拜占庭故障的容错能力对网络拓扑结构连通性的要求；（4）设计有限时间鲁棒故障检测与辨识器，快速准确检测与辨识拜占庭故障智能体，进而主动改变网络拓扑结构以实施故障隔离。本项目属于应用基础研究，为多智能体系统的分布式协同控制在实际中的应用提供安全性基础，为控制系统的安全性问题寻找新的发展生机。

英文摘要： Consensus problems of multi-agent systems have wide applications in the civil and military fields. However, the lack of a centralized entity that monitors the activity of all the agents makes multi-agent systems be prone to external malicious attacks, resulting in the performance deterioration. Therefore, it is of importance to study the security issues on consensus of multi-agent systems. For networked multi-agent systems with multiple communication delays, measurement noises and Baizantine faults, in this proposal we plan to carry out the following research. First, we will model the consensus of multi-agent systems with multiple communication delays, measurement noises and Byzantine faults. Second, we will analyze whether multi-agent systems achieve consensus and validity, and find the conditions guaranteeing the achievement of consensus and validity. Third, in order to reduce the dependence of fault tolerance to Byzantine faults on the network connectivity, we will design novel robust consensus protocols. Fourth, we will develop finite-time robust fault detectors and identifiers, the goals of which are to fast and accurately detect and identify Byzantine faults and then to carry out fault isolation by changing the network topology actively. This project is the application-oriented theory research, might provi
