Dear Editor, This letter aims to investigate the problem of attack detection and state estimation when the system suffers from external malicious attacks. A finite-time reduce-order observer is designed, which can achieve attack detection at the preset time instant. Meanwhile, it is shown that the protection of the key nodes greatly improves the efficiency of secure state estimation. Finally, the proposed theory is applied to a general cyber-physical system to illustrate its effectiveness.

Dear editor,Multi-robot systems have been employed in more and more areas in recent years due to their high efficiency, low cost and impressive robustness. When the number of agents is large, efective control of the multi-agent systems becomes a challenging problem due to the infeasibility of centralized control. One promising strategy is to control only the shape of the system instead of the precise relative positions of the robots [1].

Leader-Follower Bipartite Consensus over Directed Co-op Network with Leader’s Bounded Input

第40届中国控制会议

作者： Tao Xu yuezu lv Xiaoxu lv Zhisheng Duan Department of Mechanics and Engineering Science Peking University School of mathematics Southeast University

This paper studies the consensus problem for general linear networked systems subject to uniform quantization effect on directed topologies. A control framework consisting of a distributed control protocol and a dynamic event-triggering rule is developed to guarantee that the consensus error can exponentially converge to a bounded and adjustable set without bringing about Zeno phenomenon. Compared with traditional consensus problem requiring the continuous-time communication, the information transfer between adjacent agents in this paper only occurs at certain discrete instants at which specific events are triggered. Under the proposed dynamic event-based communication mechanism, the costs on the communication and computation can be further saved. Another distinct feature of this paper lies in that the designed control framework is applicable to directed strongly connected networks, which is more practical than existing results that are only suitable for undirected connected ***, numerical simulation results are presented to confirm the validity of the theoretical results.

第三十九届中国控制会议

作者： Xiaoya Nan yuezu lv Zhisheng Duan State Key Laboratory for Turbulence and Complex Systems Department of Mechanics and Engineering Science College of Engineering Peking University School of Mathematics Southeast University

This paper investigates the leader-followers bipartite consensus for linear multiagent systems on directed competition and cooperation network（Co-op network）. To tackle leader’s unknown input, the methodology in sliding mode control is borrowed to generate novel distributed adaptive protocol. Theoretical proof is given to demonstrate the bipartite consensus achievement under the proposed protocol. Numerical simulation is presented to illustrate our main result.
