Summary:This brief deals with a consensus control problem of a multiagent system (MAS) under deception attack in frequency domain. Deception attack is modeled and analyzed in a new framework of MAS in frequency-domain where each agent is an integrator time delay system. Unlike a blind attack, the deception attack is analyzed based upon the internal model principle (IMP) which can be injected by the attacker in two aspects. First, if an attacker holds information about the dynamics of agents or their topology structure, such kind of deception attack is known as an IMP-based attack otherwise non IMP-based attack. Sufficient and necessary conditions of resiliency are derived for both types of deception attacks using graph theory. A robust H 2 resilient controller is designed for performance tracking and consensus of the MAS using internal stability method. Simulation results demonstrate the effectiveness of the proposed method.
