A State Estimation Method for Multi-Layered Complex Dynamic Networks

Abstract

The invention discloses a method for state estimation of a multi-layer complex dynamic network, which comprises the following steps: (1) establishing a mathematical model of a multi-layer dynamic network with different numbers of nodes and different types of nodes in each layer, and non-one-to-one correspondence between inter-layer nodes; (2) ) set up a state observer network with the same topology and node dynamics as the multi-layer dynamic network; (3) establish the error dynamics of the state observer network and the multi-layer dynamic network; the error is the node of the multi-layer dynamic network (4) Design the control parameters of the state observer network according to the asymptotic stability of the error dynamics; (5) Obtain the state estimation value of the multi-layer dynamic network. The present invention realizes the state estimation of the multi-layer dynamic network with different numbers of nodes and different types of nodes in each layer, and non-one-to-one correspondence between the nodes between layers, and realizes the difference between the node state of the realized state observer network and the node state of the original multi-layer dynamic network. The error between them can converge to zero within 1.5 seconds and remain stable.

Description

technical field [0001] The invention relates to a network state estimation method, in particular to a state estimation method of a multi-layer complex dynamic network. Background technique [0002] Complex dynamic networks are formed by the coupling of many nodes and are used to describe various systems in the real world, such as communication networks, power networks, cellular neural networks, and social relationship networks. Since the discovery of the small-world and scale-free properties of complex dynamic networks, the research on complex dynamic networks has received more and more attention from various fields. [0003] Due to the large number of complex dynamic network nodes and the intricate connection between them, limited by communication mechanisms, working environments, and network bandwidth, generally only part of the state information of network nodes can be measured, and it is difficult to measure all state information of network nodes. In order to better und...
