摘　　要：安全决策与控制是保证控制系统稳定安全运行的核心支撑技术,现代网络系统在物理层面、信息层面、个体决策和监管层面分别会出现部件损坏、网络攻击和恶意决策等完全不同类型的异常行为.鉴于此,首先总结各类异常行为的特点,指出网络系统安全决策与控制的目标与难点,强调容错博弈控制相较于其他容错控制和博弈方法的特色和优势;其次,聚焦于4个层面上的各类异常行为及其特点,阐述容错博弈控制的基本问题和思想,立足于跨层调节的思路,详细总结各类容错博弈控制的最新研究成果及其特性;再次,以集群飞行器系统作为典型对象阐述容错博弈控制的应用前景;最后,对容错博弈控制在现代网络系统中的研究方向进行展望.Safe decision and control is one of the most significant technologies that ensure stable and safe operations of control systems.Three different types of abnormal behaviors,namely physical faults,cyber attacks and malicious decision may take place respectively on the physical,cyber,individual decision and supervisory layers of the modern network systems.Firstly,this paper summaries the characteristic of each abnormal behavior,and points out the goals and difficulties in the safe decision and control of network systems.The features and merits of the fault-tolerant game control is emphasized by comparing to the other fault-tolerant control methods and game methods.Secondly,this paper focuses on characteristics of these abnormal behaviors and introduces the basic problems and main ideas of fault-tolerant game design based on the cross-layer adjustment.The latest works on fault-tolerant game methods are summarized with respect to their features.An example of the swarm control systems is taken to illustrate the application prospects of fault-tolerant game control.Finally,some prospectives are also provided.
