“…Digital twins can be integrated through the digital thread to MBSE tool suites, and potentially become a core element of model-based systems engineering (MBSE). In fact, MBSE can serve as the starting point for the digital thread [15][16][17]. Using data gathered from IoT, system simulations can be run to explore failure modes, leading to progressive design improvements over time.…”

Digital twin, a concept introduced in 2002, is becoming increasingly relevant to systems engineering and, more specifically, to model-based system engineering (MBSE). A digital twin, like a virtual prototype, is a dynamic digital representation of a physical system. However, unlike a virtual prototype, a digital twin is a virtual instance of a physical system (twin) that is continually updated with the latter’s performance, maintenance, and health status data throughout the physical system’s life cycle. This paper presents an overall vision and rationale for incorporating digital twin technology into MBSE. The paper discusses the benefits of integrating digital twins with system simulation and Internet of Things (IoT) in support of MBSE and provides specific examples of the use and benefits of digital twin technology in different industries. It concludes with a recommendation to make digital twin technology an integral part of MBSE methodology and experimentation testbeds.

The risk of failure for aerospace missions can be reduced if architects model the product in a systematic way and make decisions for physical implementation based on stakeholder needs. Satellite communication system architecting should take one of its dominating elements, the communication satellite, into account for consistent modeling during the whole product lifecycle. Model-based system engineering (MBSE) serves as a useful tool for system modeling activities and connections with manufacturing. In this paper, satellite communication system architecting is investigated in the preliminary design stage via MBSE methodologies and the system modeling language (SysML). Application scenarios and use cases are built up aiming at satisfying stakeholder needs. System black-box analysis and white-box logical decomposition are further realized. The logical architecture is then partitioned for physical implementation and system optimization is carried out to give architecting suggestions. Requirement traceability is examined to finish the current design stage. The models realized by the MBSE method are reusable and easily extendible to detailed system design and implementation in the whole product lifecycle.

A Methodology for Real-Time HiL Validation of Hydraulic-Press Controllers Based on Novel Modeling Techniques

Industrial machines commissioning consumes a great amount of man-hours, due to control designers lack of knowledge about the final controller gains before they start working with it. Virtual commissioning has been postulated as an optimal solution to deal with this lack of knowledge when the Real-Time simulation of the digital models reproduces an identical behaviour as the industrial machines they represent. Cyber-Physical Systems (CPSs) offer new opportunities in this field, however, in the case of industrial machines, acquiring this level of accuracy requires to slow down the simulation. On this paper, novel modelling techniques for industrial CPSs have been presented. They are introduced to help in the evolution from conventional control design to a virtual commissioning process combining software and hardware capabilities. This methodology has been tested with a hydraulic-press model designed following manufacturer specifications, initially under a Software in the Loop (SiL) validation platform and, afterwards, in a Hardware in the Loop (HiL) validation platform. The control algorithms are designed in laboratory conditions harmless for the machine, embedding them later in the industrial environment without further modifications.
