Optimal Kinematic Control of an Autonomous Underwater Vehicle [PDF]
IEEE Transactions on Automatic Control, 2009 This note investigates the motion control of an autonomous underwater vehicle (AUV). The AUV is modeled as a nonholonomic system as any lateral motion of a conventional, slender AUV is quickly damped out. The problem is formulated as an optimal kinematic control problem on the Euclidean Group of Motions SE(3) , where the cost function to be minimized ...

Cooperative Localization for Autonomous Underwater Vehicles [PDF]
The International Journal of Robotics Research, 2008 This paper describes an algorithm for distributed acoustic navigation for Autonomous Underwater Vehicles (AUVs). Whereas typical AUV navigation systems utilize pre-calibrated arrays of static transponders, our work seeks to create a fully mobile network of AUVs that perform acoustic ranging and data exchange with one another to achieve cooperative ...
