Abstract

The development of digital twins, a virtual replica of a physical system or resource, is an emerging technology that has gained interest among researchers due to the ease of system monitoring and data analysis that is supported through its use. This paper considers the case of discrete dynamic systems, with single degree of freedom, as the physical model whose real time digital twin is to be implemented. The equation of motion of such a system is expressed as a differential equation, which depends on two variables � instantaneous time and slow time. We demonstrate the design, simulation and synthesis of the digital twin on a Field Programmable Gated Array (FPGA) by considering the two individual cases � evolution of the digital twin as a function of stiffness, and as a function of mass. The data collected for the digital twin is through sensors placed on the physical system, which procure the time response and its corresponding damped natural frequency. The programming, optimization and simulation are carried out using the simulation software Modelsim � Intel FPGA Starter Edition 19.1 for Windows. For the synthesis of the program, we make use of the Quartus Development Pro Lite Edition 19.1 on the FPGA device Cyclone V-5CGTFD9E5F35C7, by Intel. An approximation of the digital twin model is proposed. Finally, a performance analysis of the FPGA digital twin is conducted to measure its accuracy with respect to the results of the software digital twin. © 2022, American Institute of Aeronautics and Astronautics Inc, AIAA.
