First pulse technique for brushless DC motor standstill position detection based on iron B-H hysteresis

Yves Perriard, Miroslav Markovic, Omar Scaglione

This paper introduces a promising technique, called the first-pulse technique, for detecting the rotor position of a brushless DC motor at standstill. The technique is based on the B-H hysteresis characteristics of the stator iron. Depending on the rotor p ...

Structural and Resting State Functional Connectivity of the Subthalamic Nucleus: Identification of Motor STN Parts and the Hyperdirect Pathway

Jean-Philippe Thiran, Leila Cammoun, Bram Platel

Deep brain stimulation (DBS) for Parkinson's disease often alleviates the motor symptoms, but causes cognitive and emotional side effects in a substantial number of cases. Identification of the motor part of the subthalamic nucleus (STN) as part of the pre ...

High-angular-range electrostatic rotary stepper micromotors fabricated with SOI technology

Martinus Gijs, Christophe Yamahata, Marc Stranczl

Flexible bearings are advantageous for microelectromechanical systems as they enable precise, accurate, repeatable, and reliable motion without frictional contact. Based on the principle of a rotary folded-beam suspension, we have designed, fabricated, mod ...

Experimental changes in bodily self-consciousness are tuned to the frequency sensitivity of proprioceptive fibres

Olaf Blanke, Jane Aspell, Estelle Palluel

Several lines of evidence suggest an important implication of proprioceptive signals in bodily self-consciousness. By manipulating proprioceptive signals using muscle vibration, here, we investigated whether such effects depend on the vibration frequency b ...

Method for a switching loss reduction in PM drives

Andreas Gassner

Energy saving becomes more and more important. Therefore different improvements have been made in motor design, electronic devices and software in order to increase the overall efficiency of electronic motor drives. Permanent Magnet Synchronous Motors (PMS ...

Power Quality Application of Hybrid Drivetrain

Hardi Hõimoja

This paper presents a study on the power conditioning features of hybrid powertrain, especially regarding diesel-electric locomotives. Equipped with an embarked energy buffer for diesel generator support and utility grid interface, such a locomotive can be ...

Agency, gait and self-consciousness

Olaf Blanke, Oliver Alan Kannape

Agency is an important aspect of bodily self-consciousness, allowing us to separate own movements from those induced by the environment and to distinguish own movements from those of other agents. Unsurprisingly, theoretical frameworks for agency such as c ...

Quotient-method Algorithms for Input-affine Single-input Nonlinear Systems

Willson Sudarsandhari Shibani

Many real-world systems are intrinsically nonlinear. This thesis proposes various algorithms for designing control laws for input-affine single-input nonlinear systems. These algorithms, which are based on the concept of quotients used in nonlinear control ...

Modular DC/DC Converter for DC Distribution and Collection Networks

Stephan Kenzelmann

A major change in the electrical transmission and distribution system is taking place in Europe at the moment. The shift from a centralised energy production to a distributed generation profoundly changes the behaviour of the grid. Environmental or social ...

Control of Current in AC Induction Machines with Pronounced Slot Harmonics for Smooth Torque

Nicolas Lorétan

AC introduction motors have been used in traction applications for a long time. They have a good efficiency for a low cost and are very robust. Most of these motors have been developed for industrial applications and they have a torque ripple because of th ...
