Experimental Investigation on the Performances of a Multilevel Inverter Using a Field Programmable Gate Array-Based Control System

2019

The Field Programmable Gate Array (FPGA) represents a valid solution for the design of control systems for inverters adopted in many industry applications, because of both its high flexibility of use and its high-performance with respect to other types of digital controllers. In this context, this paper presents an experimental investigation on the harmonic content of the voltages produced by a three-phase, five level cascaded H-Bridge Multilevel inverter with an FPGA-based control board, aiming also to evaluate the performance of the FPGA through the implementation of the main common modulation techniques and the comparison between simulation and experimental results. The control algorithm…

A General Investigation on the Differential Leakage Factor for Symmetrical and Asymmetrical Multiphase Winding Design

2020

This work provides an investigation based on a fast estimation of the degree of unbalance (D.U.%) and the differential leakage factor (&sigma

Analysis a DSP Implementation and Experimental Validation of a Loss Minimization Algorithm Applied to Permanent Magnet Synchronous Motor Drives

2004

In this paper a new loss minimization control algorithm for inverter-fed permanent-magnet synchronous motors (PMSM), which allows to reduce the power losses of the electric drive without penalty on its dynamic performances, is analyzed, experimentally realized and validated. In particular, after a brief recall of two loss minimization control strategies (the "search control" and the "loss-model control"), both a modified dynamic model of the PMSM, which takes into account the iron losses, and a "loss-model" control strategy, are treated. Experimental tests on a specific PMSM drive employing the proposed loss minimization algorithm were performed aiming to validate the actual implementation.…

Ideazione e attuazione di un Convegno

2020

Il Convegno, nell’ideazione e nell’attuazione, ha avuto un taglio strettamente culturale e, in maniera specifica, storico-filosofico, consono alla stessa sede dell’iniziativa. L’intento era ed è rimasto, durante i lavori, sempre quello di studiare, attraverso ricerche bibliografiche ed archivistiche, il rapporto dei fratelli Mario e Luigi Sturzo e di verificare l’esistenza di un loro comune progetto cristiano di democrazia. The Conference, in its conception and implementation, has had a break strictly cultural and, in a specific, historical-philosophical way, appropriate to the same location of the initiative. The intent was and has remained, during the works, always that of studying, throu…

Athletic performance in competitive sports relies heavily on the ability to cope effectively with stressful situations. In contrast, some athletes report that their thoughts revolve around the future or past and not around the actual demands during competitions. In those specific stressful situations, the lack of focus like an unintended fixation on repetitive cognitions can have fatal consequences with regard to the performance. Especially when competitors are close in their athletic capabilities, differences in effectively coping with stress and mental stability may decide about winning and losing. One established factor of performing effectively under pressure is the individual tendency …

Corallaria

2021

Prima delle sette commedie composte dall’umanista ferrarese Tito Livio Frulovisi (1400-1463 c.), la Corallaria è caratterizzata da un doppio intreccio, entro il quale si individuano frequenti contaminazioni fra temi di tradizione comica classica e motivi di origine novellistica. Rappresentata a Venezia nel 1432, probabilmente da una compagnia di attori professionisti, la Corallaria si configura come una commedia “stataria”, dal momento che la maggiore parte degli eventi che vi si verificano, piuttosto che direttamente rappresentata, viene raccontata dai personaggi. Il titolo, di stampo evidentemente plautino, deriva dai coralli che il giovane Miles si fa prestare da Faceto e regala alla vec…

Coupled Electromechanical Analysis of a Permanent-Magnet Bearing

2017

In this paper we present a new Permanent Magnets (PMs) bearing, which is composed of a rotor capable to levitate at a short distance from a dedicated stator. Proper configurations of PMs arranged on both the stator and the rotor allows having the magnetic suspension. Intrinsic mechanical instability characterizes the device; a passive stabilization is attempted exploiting eddy currents on a conducting sheet that surrounds the magnets on the stator. The system has been simulated by means of a dedicated numerical code that takes into account the effects of magneto-mechanical coupling. The coupled problem has been integrated by means of a prediction-correction nested scheme. Some interesting r…

High Performance FOC for Induction Motors with Low Cost ATSAM3X8E Microcontroller

2018

In this paper the Authors present the Arduino Due board application for an induction motor field oriented control (FOC) algorithm. The low cost Arduino Due board is equipped with a ATSAM3X8E microcontroller that performs the algorithm calculation, data processing, current signals and speed/position data acquisition. The control algorithm has been developed with the help of the open source Arduino integrated development environment, whereas a user friendly control interface, used to manage the speed or position set point, has been developed in Java language by means of an other open source software, namely, Processing. An experimental test bed has been set up in order to validate the FOC sys…

A comparison of different DC-DC converters for energy storage management in nearly-Zero Energy Buildings

2020

In the recent years, there has been a notable interest towards renewable sources, energy saving and efficiency optimization, in order to reduce the damages brought by fine dust and greenhouse gases in terms of safety, health and environmental protection. In the building sector renewable sources and energy efficiency optimization are leading to a large scale employment of nearly-Zero Energy Buildings (n-ZEBs), meaning that the balance between produced and required energy is negligible. For a proper n-ZEB implementation, a power system architecture has to be accurately designed, according to the existing renewable sources, loads and storage systems. In this paper, an investigation on differen…
