Tracking control of an underactuated unmanned underwater vehicle [PDF]
Proceedings of the 2005, American Control Conference, 2005., 2005 In this paper, a robust position tracking controller is developed for an autonomous, underactuated, unmanned underwater vehicle (UUV). Specifically, the proposed controller forces the three dimensional (i.e., longitudinal, latitudinal, and depth) position tracking error to within an arbitrarily small region about zero (i.e., global exponential ...

Efficient dynamic simulation of an unmanned underwater vehicle with a manipulator [PDF]
Proceedings of the 1994 IEEE International Conference on Robotics and Automation, 2002 In this paper, an efficient dynamic simulation algorithm is developed for an unmanned underwater vehicle (UUV) with a robotic manipulator. It is based on an efficient O(N) algorithm where N is the number of links in the manipulator, and has been extended to include the full effects of a mobile base and various hydrodynamic forces that are exerted on ...
