This paper addresses the cooperative path-following problem of multiple marine surface vessels with unknown dynamics. Backstepping technique, neural network (NN) adaptive approach and graph theory are brought together to design the controller, where the constraints imposed by the communication network are explicitly taken into account. The path-following controller is designed such that the unknown dynamics can be compensated for by NN. The desired coordinated behavior is achieved by means of consensus on the path parameters. Simulations are conducted on a system consisting of three vessels where the results demonstrate the method.
