Prospects on Brain-Machine Interfaces for Space System Control

José del Rocio Millán Ruiz, Anna Buttfield, Pierre Ferrez

The dream of controlling and guiding computer-based systems using human brain signals has slowly but steadily become a reality. The available technology allows real-time implementation of systems that measure neuronal activity, convert their signals, and t ...

Tracking the Multi Person Wandering Visual Focus of Attention

Daniel Gatica-Perez, Jean-Marc Odobez, Silèye Oumar Ba, Kevin Smith

Estimating the {\em wandering visual focus of attention} (WVFOA) for multiple people is an important problem with many applications in human behavior understanding. One such application, addressed in this paper, monitors the attention of passers-by to outd ...

Probabilistic analysis of turbulent structures from two-dimensional plasma imaging

Ambrogio Fasoli, Ivo Furno, Benoît Labit, Mario Ludovico Podesta, Francesca Maria Poli, Gennady Plyushchev

A method is presented to construct object-related structure observables, such as size, mass, shape, and trajectories from two-dimensional plasma imaging data. The probability distributions of these observables, deduced from measurements of many realization ...

Observability analysis and state observers for automotive powertrains with backlash: a hybrid system approach

Giancarlo Ferrari Trecate

In this paper, the observability properties of automotive powertrains with backlash are analysed. We model the powertrain as a hybrid system in the piecewise affine form and use measurements of the torque and the angular speed of the engine for computing t ...

A logarithmic-time solution to the point location problem for closed-form linear MPC

Colin Neil Jones

Closed-form Model Predictive Control (MPC) results in a polytopic subdivision of the set of feasible states, where each region is associated with an affine control law. Solving the MPC problem on-line then requires determining which region contains the cur ...

Proposal strategies for joint state-space tracking with particle filters

Volkan Cevher

A proposal function determines the random particle support of a particle filter. When this support is distributed close to the true target density, filter's estimation performance increases for a given number of particles. In this paper, a proposal strateg ...

Spatial Representation and Navigation in a Bio-inspired Robot

Wulfram Gerstner, Ricardo Andres Chavarriaga Lozano, Thomas Strösslin

A biologically inspired computational model of rodent repre-sentation?based (locale) navigation is presented. The model combines visual input in the form of realistic two dimensional grey-scale images and odometer signals to drive the firing of simulated p ...

Advanced Fuel Cell System Control through State Space Modelling

Alfred Rufer, Félix Grasser

Maintaining a fuel cell system in correct operating conditions when subjected to fast load changes requires good system control. In order to design such a controller, a simple PEFC system model describing all the important system dynamics and cross couplin ...

Improving tokamak vertical position control in the presence of power supply voltage saturation

Philippe Müllhaupt, Jonathan Bryan Lister, Jean-Yves Favez

The control of the current, position and shape of an elongated cross-section tokamak plasma is complicated by the so-called instability of the current vertical position. Linearized models all share the feature of a single unstable eigenmode, attributable t ...

Coordinating Agile Systems through the Model-based Execution of Temporal Plans

Thomas Léauté

Agile autonomous systems are emerging, such as unmanned aerial vehicles (UAVs), that must robustly perform tightly coordinated time-critical missions; for example, military surveillance or search-and-rescue scenarios. In the space domain, execution of temp ...
