Abstract
Cyber-physical systems revolve around context awareness, empowering objective-oriented services, products and operations based on real data. Self-aware and self-control systems are core elements in the Industry 4.0 framework towards self-sustainable adaptive manufacturing and personalized services. This development is witnessed by the context-aware pervasive assistance to users and machines in decisions making process for optimizing product performance and economic yield. While integration of the virtual and the physical world entails smart sensors communication and complex data analytics, it relies on artificial intelligence tools to manage process operations. The objective of the article is to create awareness that systems & control community must address theoretical and practical aspects from a larger perspective. Context aware control is emerging as a natural solution to maximize the use of available sensing instrumentation and the relatively low cost data logging, i.e. an important source for extracting information, interpreting and using context information and adapt its functionality to the current context of use. This article presents a concise overview of applications where context aware systems and control methodologies are relevant in the seven societal challenges acknowledged by European policy-makers: Digital Society; Food; Health and Well-Being; Smart Resource Management; Urban Planning, Mobility Dynamics and Logistics; New Energy Demand and Delivery; and Society.
Highlights
Doubtless, the research community embraces vigorously the grand challenges envisioned in [1] with core elements from systems and control engineering
The proposed method was tested with the real-world bus routes, allowing 26.61% reduction of fuel consumption with respect to charge-depleting and charge sustaining control strategy, respectively 5.58% reduction compared to classical stochastic model predictive control that does not consider driver behavior model
A manifold of applications involving context awareness and Cyber Physical Systems (CPSs) have been developed in high impact industry domains and healthcare, which were analyzed in this survey
Summary
The research community embraces vigorously the grand challenges envisioned in [1] with core elements from systems and control engineering. Context-aware control systems (CACS) are proactive integrated structures that are able to action in an appropriate manner in real-time changing environment. This human-free adaptation increases usability and effectiveness by taking the monitored context into account. The objective of the article is to create awareness that systems & control community must address theoretical and practical aspects from a different perspective. Third section introduces the definitions and life cycle of context aware systems, along with suitable emerging control methodologies. The fourth section presents the context aware systems and controls classified in the seven societal challenges and referred with recent publications.
