中文摘要： 多智能体系统的一致性问题近年来受到了广泛的关注，但是，与之相关的故障检测问题研究仍处于起步阶段。本项目拟针对几种具有不同智能体动态的无领导者和追随领导者的多智能体系统，在多智能体系统一致性问题的框架下研究故障检测问题，得到有效的基于分布式未知输入观测器的故障检测方法以及跟通信网络拓扑结构相关的故障可检测条件，并将所得方法应用到海洋工程船电力系统的故障检测问题。本项目的研究目的是围绕多智能体系统的故障检测这一主题，改进现有的结果并探讨新问题，得到一系列较成体系的理论成果并初步应用于实际工程。本项目在研究过程中充分考虑通信网络的拓扑结构对故障可检测性的影响，着重降低故障检测器对通信网络全局信息的依赖，并探索智能体的可信度差异对故障可检测性的影响，因而所提出的故障检测方法更符合实际多智能体系统的特点。本项目选题紧绕多智能体系统的协调控制这一控制科学领域的热点问题，顺应了该学科的发展趋势。

英文摘要： Consensus problems for multi-agent systems have attracted a wide spread attention recently, however, the study on related fault detection problems is still in primary stage. In this project, fault detection problems for leaderless and leader-following multi-agent systems with several different types of agent dynamics will be considered under a consensus framwork. Some distributed unknown input observer based fault detection methods will be derived, together with netowork topology related fault detectability conditions.The proposed methods will be applied to fault detection problems for power plant systems of offshore engineering ships. Focusing on the subject of fault detection in multi-agent systems, the aim of this project is to improve some existing results, investigate some new problems, and initially apply the proposed results into practice. During the research process, the effect of the network topologies on the fault detecability will be fully considered. Attention will also be focused on reducing the detectors' requirements on the global information about the network topologies, and investigating the effect of agents' credibility difference on the fault detectability. Therefore, the proposed fault detection methods will be more suitable to the multi-agent systems than existing methods. The problems inves
