This article investigates the finite-time dynamical tracking for autonomous underwater vehicles by introducing an impulsive communication scheme. More precisely, the communication of the autonomous underwater vehicles is conducted by the prescribed impulsive instants, which is more applicable for the underwater communication. Based on finite-time control theory and impulsive control theory, the tracking controller for each autonomous underwater vehicle is designed and sufficient conditions are developed for achieving the dynamical tracking cooperation. In the end, a simulation example is given to demonstrate the effectiveness and advantage of the proposed approach.
