Control of supercapacitors for smooth EMA operations in aeronautical applications

In this paper the problem of reducing stress on aeronautical electric energy generators is considered. The usage of an active Energy Storage Device (a controlled supercapacitor) is considered as a quick device able to absorb or yield quickly energy peaks caused by sudden intervention of Electro-Mechanical Actuators. The control strategy considered is a second-order sliding mode approach, able to guarantee finite-time achievement of the control goal. This characteristic is then exploited by a ...

Collaborations Among Cultural Heritage Sites: A Network Analysis Perspective

Collaboration is the foundation upon which progress, innovation, and success are built across every aspect of business activity. While extensively studied in literature, with a predominant focus on profit organisations and public-private partnerships, there remains a notable gap in understanding collaborative patterns among cultural institutions. To address this gap, we adopt a network analysis perspective to explore the untapped potential of collaborations among archaeological parks in Sicil...

Investigation on the Torque to Mass Ratio of Synchronous Magnetic Couplings

This paper provides a comprehensive analysis of the torque to mass ratio for a wide range of synchronous permanent magnetic coupling geometries. The study aims to compare optimized magnetic couplings with commercially available flexible disc couplings to evaluate their relative performance and viability for various torque transmission applications. Both coaxial magnetic coupling (CMC) and axial magnetic coupling (AMC) designs are considered. Different combinations of dimensional parameters ar...

Temperature Impact on Insulation Lifetime During Electrical Endurance Tests

The winding temperature is widely recognized as the primary factor contributing to insulation degradation. However, the higher DC bus voltage intended for future transportation electrical drive systems may also promote electrical aging. To ensure insulation reliability, a comprehensive understanding of insulation degradation under both electrical and thermal stress is crucial. In this study, electrical endurance tests are conducted at various temperatures to accurately determine the impact of...

Supervised Energy Management in Advanced Aircraft Applications

A control strategy is proposed for energy management onboard the innovative More Electric Aircraft (MEA) concept. The objective is to reduce generator sizing (and weight onboard) by using battery packs as extra-energy sources. The flow of energy is regulated by a Buck-Boost Converter Unit (BBCU), suitably driven. The controller is composed of a two-layers architecture, where the bottom layer is devoted to current-tracking purposes, while the upper level takes care of the safe switching betwee...
