Title:
DISTRIBUTED SECURE STATE RECONSTRUCTION METHOD BASED ON DOUBLE-LAYER DYNAMIC SWITCHING OBSERVER
Document Type and Number:
WIPO Patent Application WO/2022/227946
Kind Code:
A1
Abstract:
Disclosed in the present invention is a distributed secure state reconstruction method based on a double-layer dynamic switching observer. The method comprises the following steps: according to a multi-agent system, constructing a dynamic model after a sensing channel of the multi-agent system is attacked; in view of a specific multi-agent system model, building a double-layer observer for each agent, constructing a suitable observation communication topology, and designing a corresponding residual generator; for an observation model, analyzing dynamic information for generating a residual threshold value, checking a magnitude relationship between each residual signal and the threshold value, dynamically switching a communication topology between observers according to a magnitude comparison result, and performing new data communication interaction; performing an iterative update by combining observation data of an observer itself and received observation information of a neighbor, so as to generate new observation data, and taking whether the residual signal is greater than the current threshold value as a criterion for determining whether a corresponding communication channel is attacked. By means of the present invention, it can be ensured that all transmission channels which are maliciously attacked are correctly identified, and the real state of a system is securely reconstructed.
