Observability analysis of 3D AUV trimming trajectories in the presence of ocean currents using range and depth measurements

António Pedro Rodrigues de Aguiar

We analyze the observability properties of the kinematic model of an autonomous underwater vehicle (AUV) moving in 3D, under the influence of ocean currents, using range and depth measurements. The results obtained shed light into the types of trajectories ...

A Model Predictive Control Scheme with Additional Performance Index for Transient Behavior

Colin Neil Jones, Andrea Alessandretti, António Pedro Rodrigues de Aguiar

This paper presents a Model Predictive Control (MPC) scheme for nonlinear continuous time systems where an extra performance index, which is not a measure of the distance to the set point, is introduced to influence the transient behavior of the controlled ...
