Research on the Cooperative Control of a Group of Autonomous Underactuated Vessels
نویسنده
چکیده
This paper considers the cooperative control of a group of autonomous underactuated vessels (AUV). The control objective for each vessel is to maintain its position in the formation while Formation Reference Point (FRP) tracks a predefined spatial path. In order to achieve this goal, we use vectorial backstepping to solve two subproblems: one is geometric task, anther is dynamic task. The former guarantees that the FRP tracks the spatial path, while the later ensures accurate speed control along the path. A dynamic guidance system with feedback from the state of all AUV ensures that they have the same priority (no leader) when moving along the path. The controller is proposed basically based on Lyapunov direct method and backstepping technique. Simulation results are presented and discussed.

متن کاملTime-Invariant State Feedback Control Laws for a Special Form of Underactuated Nonlinear Systems Using Linear State Bisection
Linear state bisection is introduced as a new method to find time-invariant state feedback control laws for a special form of underactuated nonlinear systems. The specialty of the systems considered is that every unactuated state should be coupled with at least two directly actuated states. The basic idea is based on bisecting actuated states and using linear combinations with adjustable parame...
