In this paper, we consider the consensus problem of the multiple agents control for a discrete-time case under fixed information topology. First, we design the control laws based on the neighbor to solve the consensus problem of multi-agent systems. Second, we prove that each follower can track the active leader, and consensus analysis is performed based on Lyapunov approach. Furthermore, we study the effect of disturbances on the system. Numerical simulations illustrate the theoretical results.
