Avoiding Feedback-Linearization Singularity Using a Quotient Method -- The Field-Controlled DC Motor Case

Feedback linearization requires a unique feedback law and a unique diffeomorphism to bring a system to Brunovsk´y normal form. Unfortunately, singularities might arise both in the feedback law and in the diffeomorphism. This paper demonstrates the ability ...

Electric field control of the skyrmion lattice in Cu2OSeO3

Henrik Moodysson Rønnow, Ivica Zivkovic, Helmuth Berger, Jonathan White, Krunoslav Prsa, Arash Alahgholipour Omrani

Small-angle neutron scattering has been employed to study the influence of applied electric (E-) fields on the skyrmion lattice in the chiral lattice magnetoelectric Cu2OSeO3. Using an experimental geometry with the E-field parallel to the [111] axis, and ...

Self-Organization of Spinal Reflexes through Soft Musculoskeletal Interactions

There has been a long-standing debate on the question of how basic reflexive behaviours in mammals come about. Recently, it has been hypothesized that soft musculoskeletal interactions, such as intrinsic passive dynamics, might play a crucial role in the d ...

In-field objective evaluation and analysis in ski jumping using inertial sensors

Julien Chardonnens

Ski jumping, a prestigious Olympic discipline, has been constantly evolving. Over the years, the biomechanics fundamentals of this highly technical sport have been intensively documented by investigating the jump timing, kinematics, dynamics and motor cont ...

Plug-and-Play Model Predictive Control based on robust control invariant sets

Giancarlo Ferrari Trecate, Marcello Farina

In this paper we consider a linear system represented by a coupling graph between subsystems and propose a distributed control scheme capable to guarantee asymptotic stability and satisfaction of constraints on system inputs and states. Most importantly, a ...

Optimization of the Start-up Time of a Variable Speed Pump-Turbine Unit in Pumping Mode

Jean-Jacques Simond, Christophe Nicolet, Basile Kawkabani, Yves Pannatier

This paper presents the start-up and synchronization procedures of large variable- speed pump-turbine units in pumping mode. These procedures applied to a doubly-fed induction motor-generator with three-level voltage source inverters VSI cascade in the rot ...

A Practical Solution to Mitigate Vibrations in Industrial PM Motors Having Concentric Windings

Dimitri Torregrossa, Luc Burdet, Christophe Espanet

Industry applications involving torque brushless dc motors require high efficiency over a large speed range. In order to achieve such specifications, flux weakening is necessary, which could lead to relative high electromagnetically induced vibrations and ...

Force feedback keyboard: self sensing

Yves Chevallier

Within the framework of a project consisting in developing a haptic keyboard, each key is aimed to be controlled individually in position and force. Small sized actuators has already been designed and integrated in a 64 keys force feedback keyboard. The pr ...

Vector Control of Single-Phase Voltage-Source Converters Based on Fictive-Axis Emulation

Alfred Rufer, Behrooz Bahrani, Stephan Kenzelmann

This paper presents an alternative way for the current regulation of single-phase voltage-source dc-ac converters in direct-quadrature (dq) synchronous reference frames. In a dq reference frame, ac (time varying) quantities appear as dc (time invariant) on ...

Redundant information encoding in primary motor cortex during motor tasks

Michael Christoph Gastpar

Information encoded in neuron ensembles has previously been hypothesized to be highly redundant, despite the apparent inefficiency of a redundant encoding system. The recent availability of intracortical, multi-electrode recordings has enabled the possibil ...
