Haptics based collaborative steering control in automated driving environments

Tomohiro Nakade

A vehicle's steering is a particular system in that it is exposed to individual subjective reviews based on criteria that are hard to assess quantitatively. Haptic design of such systems is a prime concern that has been at the center of industrial developm ...

Resynchronization of islanded unbalanced ADNs: Control, synchrocheck and experimental validation

Mario Paolone, Sherif Alaa Salaheldin Fahmy

The problem of securely reconnecting active distribution networks (ADNs) - e.g. microgrids - to their upstream grids at the point of common coupling (PCC) has been extensively discussed by the existing literature. The latter is commonly referred to as resy ...

The role of optic flow pooling in insect flight control in cluttered environments

Dario Floreano, Julien Jean Denis Nicolas Lecoeur

Flight through cluttered environments, such as forests, poses great challenges for animals and machines alike because even small changes in flight path may lead to collisions with nearby obstacles. When flying along narrow corridors, insects use the magnit ...

Interactive optimization for supporting multicriteria decisions in urban and energy system planning

Sébastien Cajot

Climate change and growing urban populations are increasingly putting pressure on cities to reduce their carbon emissions and transition towards efficient and renewable energy systems. This challenges in particular urban planners, who are expected to integ ...

FRIDA: FRI-Based DOA Estimation For Arbitrary Array Layouts

Martin Vetterli, Ivan Dokmanic, Robin Scheibler, Eric Bezzam, Hanjie Pan

In this paper we present FRIDA—an algorithm for estimating directions of arrival of multiple wideband sound sources. FRIDA combines multi-band information coherently and achieves state- of-the-art resolution at extremely low signal-to-noise ratios. It work ...

A Friction Compensation Control for Power Steering

Philippe Müllhaupt, Robert Fuchs

The effects of friction are critical to the dynamics of electric power steering (EPS). On the one hand, friction contributes to the stability of the system and filters some of the disturbances (road vibration, etc.). On the other hand, it affects negativel ...

Cheetah-cub-S: Steering of a Quadruped Robot using Trunk Motion

Auke Ijspeert, Peter Eckert

A reliable concept for steering was realized by in- tegrating a spine-like structure with one DoF into a quadruped robot - Cheetah-cub-S. We increased maneuverability dramat- ically compared to a robot with rigid spine, while keeping controlling effort low ...

Steerable PCA for Rotation-Invariant Image Recognition

Michaël Unser, Cédric René Jean Vonesch

In this paper, we propose a continuous-domain version of principal-component analysis, with the constraint that the underlying family of templates appears at arbitrary orientations. We show that the corresponding principal components are steerable. Our met ...

Preliminary design of the ITER ECH Upper Launcher

Olivier Sauter, Timothy Goodman, René Chavan, Jean-Daniel Landis, Francisco Sanchez

The design of the ITER electron cyclotron launchers recently reached the preliminary design level - the last major milestone before design finalization. The ITER ECH system contains 24 installed gyrotrons providing a maximum ECH injected power of 20 MW thr ...

Progress on the ITER H&D EC Upper Launcher Steering-Mirror Control System

Timothy Goodman, René Chavan, Federico Alberto Alfredo Felici, Francisco Sanchez, Robert Bertizzolo, Jean-Daniel Landis, Frédéric Dolizy

The ITER Heating and Current Drive Upper Launcher (H&CD EC UL) uses a pneumomechanical steering-mirror assembly (SMA) to steer the RF beams for their deposition in the appropriate location in the plasma to control magnetohydrodynamic activity (neoclassical ...

Wavelet Steerability and the Higher-Order Riesz Transform

Michaël Unser, Dimitri Nestor Alice Van De Ville

Our main goal in this paper is to set the foundations of a general continuous-domain framework for designing steerable, reversible signal transformations (a.k.a. frames) in multiple dimensions (d ≥ 2). To that end, we introduce a self-reversible, Nth-order ...

Progress On The Iter Upper Launcher Millimeter Wave Design And Testing

René Chavan, Federico Alberto Alfredo Felici, Frédéric Dolizy

The main purpose of the ITER ECH upper launcher is to control magnetohydrodynamic activity, in particular neoclassical tearing modes, in the plasma. The mm-wave optical system is optimized to insure that the eight RF beams are all focused to a small beam w ...

Neighboring-Extremal Control for Singular Dynamic Optimization Problems. II- Multiple-Input Systems

Dominique Bonvin, Benoît Chachuat, Sébastien Gros

Dynamic optimization provides a unified framework for improving process operations while taking operational constraints into account. In the presence of uncertainty, measurements can be incorporated into the optimization framework for tracking the optimum. ...

NCO Tracking for Singular Control Problems Using Neighboring Extremals

Dominique Bonvin, Benoît Chachuat, Sébastien Gros

A powerful approach for dynamic optimization in the presence of uncertainty is to incorporate measurements into the optimization framework so as to track the necessary conditions of optimality (NCO), the so-called NCO- tracking approach. For nonsingular co ...
