Antenne e Sensori a Microonde

The research group is active in the study, development, and testing of microwave and millimeter-wave antennas and sensors for space and terrestrial applications. Its activities include the design of innovative antennas, particularly leaky-wave antennas; the development of advanced electromagnetic methods for antennas based on periodic structures and for the analysis of scattering from natural surfaces (soil, vegetation, ocean); and the development of algorithms for the analysis and processing of satellite data, mainly acquired through Earth-observation missions.

Low-cost, high-resolution, fault-robust position and speed estimation for PMSM drives operating in safety-critical systems

In this paper it is shown how to obtain a low-cost, high-resolution and fault-robust position sensing system for permanent magnet synchronous motor drives operating in safety-critical systems, by combining high-frequency signal injection with binary Hall-effect sensors. It is shown that the position error signal obtained via high-frequency signal injection can be merged easily into the quantization-harmonic-decoupling vector tracking observer used to process the Hall-effect sensor signals.

Closed-Loop, Flux-Weakening Control of Hybrid-Excitation Synchronous Machine Drives

This paper presents a closed-loop flux-weakening controller for hybrid-excitation synchronous machine drives based on separate regulation of amplitude and phase angle of the armature voltage. Operating point analysis is carried out to investigate the dynamic properties of the drive and to give guidelines in the tuning of the controller. Finally, experimental tests validating the theoretical derivations are performed on a prototype hybrid-excitation drive.
