Coordinated control strategies for networked vehicles: an application to Autonomous Underwater Vehicles
نویسنده
چکیده
The specification and design of coordinated control strategies for networked vehicles and systems is discussed. A strategy to find the local minimum of an oceanographic scalar field with networked autonomous underwater vehicles (AUV) is presented. The strategy consists in coordinating the motions of the AUVs to implement a modified version of the simplex optimization algorithm. In the original algorithm, the scalar field is given by a function. In the modified version, the scalar field is given by the phenomenon itself. The AUVs sample the phenomenon to calculate the directions of descent, and to minimize the phenomenon along each direction of descent. The strategy is discussed in the more general context of coordination and control of networked vehicles and systems.

Adaptive Robust Control for Trajectory Tracking of Autonomous underwater Vehicles on Horizontal Plane
This manuscript addresses trajectory tracking problem of autonomous underwater vehicles (AUVs) on the horizontal plane. Adaptive sliding mode control is employed in order to achieve a robust behavior against some uncertainty and ocean current disturbances, assuming that disturbance and its derivative are bounded by unknown boundary levels. The proposed approach is based on a dual layer adaptive...

متن کاملSymmetry and Reduction for Coordinated Rigid Bodies
Motivated by interest in the collective behavior of autonomous agents, we lay foundations for a study of networks of rigid bodies and, specifically, the problem of aligning orientation and controlling relative position across the group. Our main result is the reduction of the (networked) system in the case that two individuals are coupled by control inputs that depend only on relative configura...
