Durante il 14th World Congress in Computational Mechanics and ECCOMAS Congress Marta Gatto, Fabio Marcuzzi (Università degli Studi di Padova) e Paolo Martin (Simnumerica) hanno presentato lo studio dal titolo Real-time simulation of differential models: digital twins for industrial applications.

Si seguito l’abstract della presentazione:

In this talk we will present some cases of successful interactions between mathematics and industry, where the construction of a digital twin implemented in an embedded computing device, running a realtime model of the physical plant/machine, has given a practical advantage in the design of the controlled system, mainly in the design of the control software. With the increasing widespread use of electronic controllers and the systematic efforts in data collection within industry operations, the development of mathematical models and computational methods is becoming more and more important in industry applications. In particular, we will present three real cases that involve data analysis and process control.
The first concerns the design of large-scale refrigeration plants; the second case concerns an industry 4.0 application in automated food processing machines, and the third the design of access automation systems. For each case study, we will describe the practical benefits that a parameterized mathematical model, based on differential equations and implemented as the digital twin of a future product, can make in a real industrial facility. Real-time simulation algorithms have been implemented in C and Python on low-cost embedded systems, like Raspberry Pi computers and ARM-based microcontrollers. Moreover, specific electronic hardware interfaces have been designed to couple these embedded systems with the low-voltage, analog and digital I/O ports of the electronic controllers, through their standard I/O peripherals. We will put also some emphasis on optimization issues arising from the limited computing resources offered by low-cost embedded systems when non-trivial I/O operations are required.
