Novel High Accuracy Resolver Topology for Space Applications
(MDPI, 2021)
In recent years, the space industry has experienced a significant change mainly due to the incursion of private companies, which has shaken up the sector. This new situation allows for a reduction regarding the reliability ...
Application Dependent End-of-Life Threshold Definition Methodology for Batteries in Electric Vehicles
(MDPI, 2021)
The end-of-life event of the battery system of an electric vehicle is defined by a fixed end-oflife threshold value. However, this kind of end-of-life threshold does not capture the application and battery characteristics ...
Optimum Slot and Pole Design for Vibration Reduction in Permanent Magnet Synchronous Motors
(MDPI, 2021)
Permanent Magnet Synchronous Motors (PMSMs) are increasingly being used and are required to satisfy noise and vibration specifications. Thus, it is necessary to develop design guidelines for electric motors that consider ...
Dual Inertia-Emulation Control for Interlinking Converters in Grid-Tying Applications
(IEEE, 2021)
Electric grids are undergoing several changes, mostly driven by the replacement of classical highly-inertial generators by converter-interfaced generation and storage systems. This entails the reduction of inherent inertia ...
ADAPT: an Automatic Diagnosis of Activity and Processes in auTomation environments
(IEEE, 2020)
In an automated industrial environment, a large volume of data and signals is available, both from sensors and actuators in machinery and from the interaction with operators and users. Operation diagnosis can have multiple ...
Petri net implementation in programmable logic controllers: methodology for development and validation
(IEEE, 2021)
Lead times are key to good market positioning of providers of automated solutions based on a programmable logic controller (PLC). Testing control software against a digital twin (DT) of the process, any programming errors ...
