Abstract： This paper studied a new event-triggered consensus protocol for MASs based on switching topology. Two events are designed in this protocol, including convergence events caused by agent state evolution and topology events caused by topology change. Stability analysis of public Lyapunov function related to events and consensus proof of MASs are given. A network connectivity algorithm based on constraint set is also designed to enhance network connectivity. The simulation results show that the designed event-triggered consensus protocol can make the state evolution of agents tend to be consistent and effectively reduce the update frequency of the controller of agents in the switching topology network environment, reduce the energy consumption of MASs, improve the connectivity effect of the network effectively, and provide theoretical support for the subsequent research of event-triggered control.

Abstract： Multi-agent system has always been the main research subject in many disciplines. The multi-agent collaborative control theory based on switch topology is an important part of multi-agent system research and has been a hot spot in recent years. In order to promote cooperative control theory of multi-agent based on switched topology, based on the extensive investigation of the existing literature and the latest achievements, this paper discusses the development of this field from three aspects: the consistency problem, the distributed optimization problem and the distributed estimation problem The status quo is summarized; such as the design of the agreement, the performance analysis of the agreement and its advantages and disadvantages, the realization of distributed optimization and the practical application of distributed estimation. Finally, it points out the outstanding issues in the field and the future research directions.

Abstract： Nowadays, with the rapid development of Internet of Things and big data, micro-embedded systems have been widely used in takeaway and sharing industries such as shared bikes, transportation, express delivery and smart home. Existing fault diagnosis research mainly focuses on traditional embedded systems. Therefore, relatively few fault diagnosis documents for micro-embedded systems. To solve the above problems and combine the characteristics of the system (limited computing capacity and storage space) , this paper proposes a class of fault diagnosis method classification methods suitable for miniature embedded systems, divided into two categories, namely local fault diagnosis methods and remote Fault diagnosis method. Then this paper describes the core idea of the fault diagnosis method for micro-embedded systems, summarizes the advantages and disadvantages of each method used in micro-embedded systems, and the problems that should be noted. Finally, this paper discusses the problems that need to be solved in the fault diagnosis of miniature embedded systems.
