Quasi-Consensus of Time-Varying Multi-Agent Systems with External Inputs under Deception Attacks

Entropy (Basel). 2022 Mar 23;24(4):447. doi: 10.3390/e24040447.

Abstract

The quasi-consensus of a class of nonlinear time-varying multi-agent systems suffering from both external inputs and deception attacks is studied in this paper. This is different from a time-varying matrix, which is assumed to be bounded; further reasonable assumptions are supposed. In addition, impulsive deception attacks modeled with Bernoulli variables are considered. Sufficient conditions to achieve quasi-consensus are given, and the upper bounds of the error state related to the deception attacks is derived. Finally, a numerical simulation example is provided to show the validity of the obtained results.

Keywords: deception attacks; external inputs; quasi-consensus; time-varying multi-agent systems.
