A Perching Mechanism for Micro Aerial Vehicles

Dario Floreano, Roland Siegwart, Mirko Kovac, Jürg Markus Germann

Micro Aerial Vehicles (MAVs) with perching capabilities can be used to efficiently place sensors in aloft locations. A major challenge for perching is to build a lightweight mechanism that can be easily mounted on a MAV, allowing it to perch (attach and de ...

Control of a multilevel modular DC/DC converter for mobile applications

Alfred Rufer, Daniel Montesinos Miracle

This paper presents the control design of a multilevel modular DC/DC converter for regenerative braking systems in mobile applications. The proposed control scheme is able to control the energy flow between supercapacitors and the DC link and equalizing th ...

Torque Measurement Methods for Very High Speed Synchronous Motors

Yves Perriard, Pierre-Daniel Pfister

The article presents two different torque measurement methods for very high speed synchronous motors: one uses an eddy current brake, and the other is an inertial method. The article also presents a ball bearings friction torque measurement method designed ...

Comparative study and selection criteria of linear motors

Samuel Chevailler

Initially, linear motors have been particularly dedicated to transportation systems. Nowadays, linear motors are meant to replace a system using a rotating motor and a transmission to realize a linear movement. With linear motors the performances increase ...

Haptic instrumentation for an interventional radiology simulator

Dejan Ilic

Low trauma, reduced costs and fast recovery are only a few factors why minimally invasive surgery (MIS) is taking over classical surgical methods. Interventional Radiology (IR) is a minimally invasive procedure where thin tubular instruments are steered th ...

Analytical and numerical modeling of an ultrasonic stepping motor using standing waves

Yves Perriard, José Fernandez Lopez

Piezoelectric motors (usually called ultrasonic) show interesting characteristics. Not only they deliver high torques at low speeds but their structure confers to them a braking torque without energy supply. This paper firstly present a list of possible so ...

Voltage stresses on PWM inverter fed induction motors : cable modeling and measurement.

Jean-Jacques Simond, Basile Kawkabani, Roland Wetter

The present paper deals with the determination of voltage stresses on PWM inverter fed induction motors by considering first the cable modeling and the measurement of different parameters. Then, based on this model, voltage stresses on the motor windings a ...
