This paper proposes an intermittent impulsive control scheme to realize consensus of multi-agent systems with unreliable communications. In our algorithm, the distributed impulsive controller is only activated in the control windows than during the whole time. The novel sufficient condition is derived to realize the intermittent impulsive consensus of multi-agent nonlinear systems by using the algebraic graph theory and Lyapunov stability theory. A simulation example ultimately is given to show the effectiveness of intermittent impulsive control method.
