Graph Chatbot
Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
A digital controller for piezoelectric motors was developed. The controller tunes the driving frequency in order to maximize the power transmitted to the motor. A maximum of power is absorbed when the resonant frequency of the mechanical and electrical par ...
The aim of this project is to model and optimise a hybrid stepping motor that drives a closed-circuit television (CCTV) dome camera mechanism. It starts with an implementation of the geometry in ProEngineer (CAD). Then, with the aid of readings and 2D fini ...
Iterative Learning Control (ILC) is a technique used to improve the tracking performance of systems carrying out repetitive tasks, which are affected by deterministic disturbances. The achievable performance is greatly degraded, however, when non-repeating ...
An important issue in nanoelectromechanical systems is developing small electrically driven motors. We report on an artificial nanofabricated motor in which one short carbon nanotube moves relative to another coaxial nanotube. A cargo is attached to an abl ...
This paper presents the design, the properties, and the optimization study of a new type of ultrasonic linear motor. Numerical modeling has been carried out and simulations with software have been realized. To avoid performing a large number of simulations ...
To improve the resolution of the Very Large Telescope Interferometer (VLTI) a two-stage mechanical system, a so called Differential Delay Line (DDL), is developed jointly by the EPFL and the Observatory of Geneva. The system is designed to reach nanometer ...
Industrial robotic systems often require high performance control of a number of converter-fed motors. Although the advantages of using industrial robots during the manufacturing process are numerous the initial capital cost of the robotic system can be pr ...
We present an analytical solution for the magnetic field, induced eddy currents, and the corresponding losses generated in the rotor of a slotless permanent-magnet (PM) motor. The field excitation is a current sheet placed at the stator interior surface. T ...
In order to control the speed and/or position of permanent magnet (PM) motors, they require position sensors. Basically, the auto-commutation needs 3 sensors for a 3-phase motor. In micro-motors, as there is no space for the sensors, self-sensing must be u ...
