Cyber-Physical-Systems (CPS) enable flexible and reconfigurable realization of automation system architectures, utilizing distributed control architectures with non-hierarchical modules linked together through different communication systems. Several control system architectures have been developed and validated in the past years by research groups. However, there is still a lack of implementation in industry. The intention of this work is to provide a summary of current alternative control system architectures that could be applied in industrial automation domain as well as a review of their commonalities. The aim is to point out the differences between the traditional centralized and hierarchical architectures to discussed ones, which rely on decentralized decision-making and control. Challenges and impacts that industries and engineers face in the process of adopting decentralized control architectures are discussed, analysing the obstacles for industrial acceptance and the new necessary interdisciplinary engineering skills. Finally, an outlook of possible mitigation and migration actions required to implement the decentralized control architectures is addressed.
Embedded systems are being increasingly used in changing environments where they no longer fulfill their associated stakeholder goals on their own, but rather in interaction with other embedded systems. This transition to networked, collaborative embedded systems is creating new application opportunities that impose numerous challenges for developers of these systems. In this introductory chapter of the book, we present the complexity of these systems and the challenges associated with them in a coherent manner. We illustrate the challenges using two use cases, “Vehicle Platooning” and “Adaptable and Flexible Factory.” Finally, we reference the challenges of developing collaborative embedded systems to the individual chapters of this book, which describe various methods of mastering the complexity in more detail.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
