Until now, the preferred solution for MEMS (Micro Electro Mechanical Systems) actuation is the electrostatic one. The main reason is that this kind of actuators can be easily manufactured following the microfabrication rules, as their geometry perfectly fi ...
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 ...
In this paper an Iterative Learning Control (ILC) algorithm is proposed for a certain class of Linear Parameter Varying (LPV) systems whose dynamics change between iterations. Consistency of the algorithm in the presence of stochastic disturbances is shown ...

Nowadays, more and more electrical motors are being used in mobile applications, such as hybrid cars for the automotive sector or even in aeronautics applications. A typical example is the solar impulse airplane which is propelled with four electrical moto ...
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 ...
This paper presents a 3-D finite-element modal analysis to reduce the acoustical power radiated by a brushless permanent-magnet synchronous machines and avoid any resonance phenomena. The method is able to analyze the impact of some design parameters on al ...
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 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 ...
Since control of a three-phase machine requires only two currents, it is possible to independently control a number of three-phase machines using reduced-switch-count voltage source inverter (VSI) topologies. One such configuration consists of n three-phas ...
n large cities, due to expensive land price, high-rise buildings are built, in which the space dedicated to the elevators is considerable and reduces the rented surfaces. To decrease these lost surfaces, a Multi Mobile System is proposed. It consists of se ...
