Model-based engineering for designing cyber-physical systems from product specifications

Abstract

Cyber-physical systems (CPS) are composed of independent and cooperative elements. Rapid adaptation to disturbances is an essential characteristic of CPS. One of the challenges in designing CPS is considering these specificities. Model-Based Engineering is a method for reducing complexity in system design. This paper presents a methodology for designing CPS and its control system using System Modeling Language (SysML) diagrams and IEC 61499 standard. The product's specifications are the starting point; the methodology focuses on what is produced before determining how to make it. The real-time control system is designed from high-level knowledge and tested software components on the plug and produce principle. Task-based structural analysis ensures the elements' synchronization to determine the system's general behavior.
