Validation of Complex Control Systems with Heterogeneous Digital Models in Industry 4.0 Framework

Abstract

The precise evaluation of the system design and characteristics is a challenge for experts and engineers. This paper considers the problem of the development and application of a digital twin to assess cyberphysical systems. We analyze the details of digital twin applications at different lifecycle stages. The work reviews and summarizes properties of models concerning the digital and physical components of a cyberphysical system (CPS). The other issue of a CPS is increasing cybersecurity threat for objects, so special attention is paid to the heterogeneous digital twin usage scenarios to improve CPS cybersecurity. The article also details the heterogeneous digital twin’s implementation for a real upper-level control system of a nuclear power plant. The presented heterogeneous digital twin combines virtual machines with real equipment, namely hardware-in-the-loop (HiL) components. The achievements and drawbacks of the implemented model, including single timescale maintaining challenges, are discussed.

Design, Modeling and Implementation of Digital Twins

“…Wu et al [ 122 ] review DT applications for ultra-precision machining to improve the performance and build processes of highly accurate technology components. Semenkov et al [ 123 ] analyze how DTs can assess Cyber–Physical Systems and provide a precise evaluation of the system design and characteristics. Steindl et al [ 124 ] analyze architectures and frameworks to develop a technology-independent Generic DT Architecture aligned with the Reference Architecture Model Industry 4.0 (RAMI 4.0).…”

Design for Six Sigma Digital Model for Manufacturing Process Design

“…The right answer to this challenge can be the combination of known and proven methods and tools adapted to the new conditions in society. It is no longer sufficient to carry out optimisations during the product life cycle (PLC) [1]. It is imperative to look for solutions or partial solutions in the earlier stages of defining the product and its production process.…”
