Motion Teaching Method for Complex Robot Links Using Motor Current

Conventional robot motion teaching methods use a teaching pendant or a motion capture device and are not the most convenient or intuitive ways to teach a robot sophisticated and fluid movements such as martial arts motions. Ideally, a robot could be set up ...

Frustration- induced plateaus in S >= 1/2 Heisenberg spin ladders

Frédéric Mila, Salvatore Manmana, Jean-David Picon, Tommaso Coletta, Frédéric Alexis Michaud

We study the T=0 magnetization of frustrated two-leg spin ladders with arbitrary value of the spin S. In the strong-rung limit, we use degenerate perturbation theory to prove that frustration leads to magnetization plateaus at fractional values of the magn ...

Fast polarizers installation for ECRH and ECE in TCV

Timothy Goodman, Federico Alberto Alfredo Felici, Laurie Porte

We report on the installation of fast polarizers for ECRH injection and ECE diagnostics, in the TCV tokamak. The main goal is to change the polarization during a plasma shot and react to changing conditions such as: plasma current and position, ECRH inject ...

Altered modulation of intracortical excitability during movement preparation in Gilles de la Tourette syndrome

Friedhelm Christoph Hummel

Gilles de la Tourette syndrome is a neuropsychiatric disorder in which cortical disinhibition has been proposed as a pathophysiological mechanism involved in the generation of tics. Tics are typically reduced during task performance and concentration. How ...

Motor control by sensory cortex

Carl Petersen, Varun Sreenivasan, Rachel Aronoff, Céline Matéo, Ferenc Mátyás, Fred Marbach, Catherine Wacongne

Classical studies of mammalian movement control define a prominent role for the primary motor cortex. Investigating the mouse whisker system, we found an additional and equally direct pathway for cortical motor control driven by the primary somatosensory c ...

Facilitating skilled right hand motor function in older subjects by anodal polarization over the left primary motor cortex

Friedhelm Christoph Hummel

Healthy ageing is accompanied by limitations in performance of activities of daily living and personal independence. Recent reports demonstrated improvements in motor function induced by noninvasive anodal direct current stimulation (tDCS) of the primary m ...

Dual frequency reflectarray cell using split-ring elements with RF MEMS switches

Julien Perruisseau-Carrier, Caner Güçlü

In this study, a dual frequency circularly polarized reconfigurable reflectarray (RA) cell with RF-MEMS switches is designed. RA combines the advantages of reflector-based and phased array antennas, providing a low-cost and high performance antenna array s ...

A Synchronous Current Control Scheme for Multiphase Induction Motor Drives

Drazen Dujic

Rotor-flux-oriented control of multiphase induction machines with sinusoidal magnetomotive force (MMF) distribution can be realized theoretically by using only two current controllers in the synchronous reference frame. In practice, however, this is inadeq ...

Modeling and Control of a Magnetically Levitated Planar Motor

Alireza Karimi, Roland Longchamp, Marc Kunze, Vincent Reymond

This paper deals with the modeling and control of a magnetically levitated planar motor. The actuator considered has moving coils and stationary magnets. The principal objective is to develop a model which can be implemented in simulation. Therefore, the d ...

An analytical solution for the rotor eddy current losses in a slotless PM motor: the case of current layer excitation

Yves Perriard, Miroslav Markovic, Pierre-Daniel Pfister

We present an analytical solution for the induced eddy currents and the corresponding losses generated in the rotor of a slotless permanent magnet (PM) motor. The field excitation is a current layer placed at the stator interior surface. The solution is ba ...
