Abstract
The present disclosure discloses a distributed secure state reconstruction method based on a double-layer dynamic switching observer. The method includes the following steps: constructing a dynamics model of a sensing channel of a multi-agent system after the sensing channel is attacked according to the multi-agent system; building a double-layer observer for each multi-agent in combination with a specific multi-agent system model, constructing a proper observation communication topology, and designing a corresponding residual generator; analyzing dynamic information generating a residual threshold aiming at an observation model, checking a magnitude between each residual signal and the threshold, dynamically switching the communication topology between the observers according to the compared magnitude, and performing a new data communication interaction; and performing iterative updating to generate new observation data in combination with self observation data and received neighbor observation information, and taking whether the residual signal is greater than a current threshold or not as a standard for determining whether a corresponding communication channel is attacked or not…
