A co-design scheme of event-triggered sampling mechanism and active fault tolerant control(FTC) is developed. Firstly,a fault diagnosis observer is designed to estimate both the fault and the state simultaneously by using the event-triggered sampled output. Some H∞constraints between the estimation errors and the event-triggered sampling mechanism are established to ensure the estimation accuracy. Then, based on the constraints and the obtained fault information, an event-triggered detector and a static fault tolerant controller are co-designed to guarantee the stability of the faulty system and to reduce the sensor communication ***, the problem of the event detector and dynamic FTC co-design is also investigated. Simulation results of an unstable batch reactor are finally provided to illustrate the effectiveness of the proposed method.

This paper preliminarily investigates the problem of fault tolerant control for nonuniformly sampled-data systems. Firstly, based on the analysis that the adaptive fault diagnosis observer is not appropriate for sampled-data systems, a novel augmented fault estimation observer is developed to simultaneously estimate continuous-time state and fault by use of discrete-time nonuniformly sampled output. Using the on-line fault and state information, a sampled-data state feedback fault tolerant controller which is nonuniformly updated is designed to guarantee the stability of closed-loop system in presence of faults. Finally simulation results are presented to illustrate the efficiency of the proposed method.

从攻击者的角度出发,在直流状态估计框架下提出了一种基于拓扑篡改的虚假数据注入攻击(FDIA)方案。首先,通过分析攻击后由网络拓扑处理器计算所得拓扑结构与传感器测量结果的一致性以及对比攻击前、后的残差,给出可以躲避拓扑误差处理检测以及残差检测的隐蔽攻击定义;然后,基于上述定义以及攻击向量列空间的隐蔽条件,提出一种FDIA方案,通过求解凸规划问题实现在保证隐蔽性的同时获得最大发电收益;最后,基于标准IEEE 9节点及14节点系统对所提方案的有效性进行验证。结果表明,与现有FDIA方案相比,所提将拓扑篡改与FDIA相结合的攻击方案具有更强的隐蔽性且获利更大。
