Novel Generalised Notch Filter for Harmonic Vibration Suppression in Magnetic Bearing Systems

Yves Perriard, Douglas Martins Araujo, Leopoldo Rossini, Guzmán Borque Gallego

Magnetic bearings represent an important alternative to conventional ball bearings for applications that require very low noise and vibrations. The absence of contact and friction between rotor and stator parts, combined with the use of active vibration co ...

Force Analysis of a Slotless Lorentz-Type Active Magnetic Bearing Actuator

Yves Perriard, Douglas Martins Araujo, Leopoldo Rossini, Guzmán Borque Gallego

This article presents the analysis of the three-dimensional forces applied by a slotless Lorentz-type fully-active magnetic bearing actuator. An analytical model is presented for defining the forces applied by every radial and axial bearing of the actuator ...

Linear Parameter-Varying Kalman Filter for angular velocity estimation of a reaction sphere actuator for satellite attitude control

Alireza Karimi, Leopoldo Rossini, Guzmán Borque Gallego

This paper presents a novel angular velocity estimation strategy of a Reaction Sphere (RS) for satellite attitude control based on a Linear Parameter-Varying (LPV) Kalman Filter. The reaction sphere is a permanent magnet synchronous spherical actuator whos ...

Closed-loop magnetic bearing and angular velocity control of a reaction sphere actuator

Yves Perriard, Leopoldo Rossini

This article presents the first closed-loop magnetic bearing and angular velocity experimental results of a reaction sphere actuator for satellite attitude control. The proposed reaction sphere is a permanent magnet spherical actuator whose rotor is suppor ...

Does an intraneural interface short-term implant for robotic hand control modulate sensorimotor cortical integration? An EEG-TMS co-registration study on a human amputee

Silvestro Micera, Leopoldo Rossini

Purpose: Following limb amputation, central and peripheral nervous system relays partially maintain their functions and can be exploited for interfacing prostheses. The aim of this study is to investigate, for the first time by means of an EEG-TMS co-regis ...
