This article considers the robust cooperative control problem of multiple double-integrator agents' formation moving around a set of given curves on spheres, where each agent suffers an unknown spatiotemporal flowfield and the communication topology among agents is directed. The flow specification is composed of a general direction matrix and a responding unknown flow speed vector, which includes...
This paper considers the cooperative control problem of second-order agents formation tracking a set of given curves on spheres when each agent suffers an unknown spatiotem-poral flowfield. The flowfield under consideration is composed of three known base vectors and the unknown corresponding coefficients. A novel coordinated adaptive estimator is proposed to estimate the unknown flow coefficients...
This paper considers the problem of directing a family of underactuated ships to formation tracking a set of closed orbits and achieve attitude synchronization. It shows that our previous concentric compression design is useful to the coordinated motion of underactuated ships. The condition that the total linear speed of each ship is greater than zero is ensured by introducing a potential function...
This paper addresses the problem of coordinated path-following and attitude control design for a group of fully actuated surface vessels on given convex loops. By incorporating the curve extension design with the consensus-based design we propose a solution to the formation and attitude coordination control. It removes the assumption of nonzero total speed of each vessel that is presented in the literature...
