1. µ-synthesis for unmanned underwater vehicles current disturbance rejection
This note focuses attention on a novel approach to disturbance rejection when the µ-synthesis control procedure is applied to Unmanned Underwater Vehicles (UUVs). Environmental external disturbances simplify to ocean current for a totally submerged vehicle and greatly contributes for hydrodynamical loads and the tether cable disturbance. Our case scenario d

2. Experimental methodology for the obtaining of the hydrodynamic parameters of VSNT JAHU II, based in digital image processing. / Metodologia experimental para obtenção dos parâmetros hidrodinâmicos do VSNT JAHU II, baseado em processamento digital de imagens.
Unmanned underwater vehicles they have been used continually by the planet in spite of the difficulties of your operation, both for scientific observation, but also for monitoring of engineering works. The positions of these vehicles are controlled, in general, which makes manually they work long and tiring to their pilots. An alternative that simplifies thi

4. Modelagem e identificação de parâmetros hidrodinâmicos de um veículo robótico submarino. / Modelling and Identification of hydrodynamic parameters of an underwater robotic vehicle.
In this work, a procedure for experimental identification of hydrodynamic coefficients of unmanned underwater vehicles is presented. At first, the development of a testbed for research on dynamics, control, and navigation of underwater vehicles is presented. This experimental platform includes: 1) a open-frame semi-autonomous unmanned underwater vehicle name
