Event-driven time-varying coupled complex dynamic network synchronization method

Abstract

The invention belongs to the technical field of intelligent control, and discloses an event-driven time-varying coupled complex dynamic network synchronization method. The cooperative directed spanning tree topology gives a sufficient condition for realizing time-varying complex dynamic network index synchronization and a strict positive lower bound of event-driven interval time so as to eliminatethe Zeno behavior. The cooperative directed spanning tree topology allows that the nodes in the network are not connected any time, and only the integration of the Laplacian matrix of the network topology requires to include a directed spanning tree within a period T so that the requirement of network communication for the network topology can be reduced. A theoretical basis can be laid for application of time-varying coupled complex dynamic network synchronization and the range of application can be extended; and the communication traffic between the network nodes can be reduced, the networkbandwidth can be saved and the communication cost can be saved.

Description

technical field [0001] The invention belongs to the technical field of intelligent control, in particular to an event-driven time-varying coupling complex dynamic network synchronization method. Background technique [0002] Since the emergence of small worlds and scale-free networks at the end of the last century, complex networks have attracted extensive attention from researchers in the fields of natural science and engineering. Many networks in real life can be described by complex network models, such as the Internet, the World Wide Web, biological networks, social networks, transportation networks, communication networks, aviation networks, distribution networks, and so on. A complex dynamic network consists of many coupled dynamic nodes, and each node has the same dynamic equation without coupling. In recent years, complex dynamic network synchronization has become a hot topic in the field of intelligent control, and has aroused great interest of many researchers in ...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the existing technology are: the fixed network topology or the undirected connected topology cannot completely solve the existing practical problems, so that the transmission of node information has higher requirements on the network topology, while the directed time-varying disconnected topology The structure is random, the theoretical analysis is very difficult, and the practical application lacks theoretical support

In addition, due to the large network scale and large number of nodes in the existing complex dynamic network, continuous communication is adopted, resulting in a very large communication volume, which leads to network bandwidth congestion and increased communication costs.
