A Review of Co-Design Approaches and Tools for Control of Cyber-Physical Systems

Abstract

Systems that integrate between computers, communication and control systems are known as Cyber-Physical Systems (CPSs), and effective control of such systems is challenging. With advancement of the related areas and many systems are inter-connected, CPSs are becoming important elements especially in Industry 4.0 and 5.0. This paper presents a review of co-design approaches for control of CPS, in which desired performance in both layers (cyber and physical) are considered during the controller design. The approach is found to be suited well for CPS. Moreover, in this paper, a special focus is given to event-based control approaches as promising results are reported. In this case, event-based state-space and PID controllers are reviewed. In addition, tools used for the development and performance analyses of co-design approaches are discussed. Several control challenges related to CPS control have also been identified. It is envisaged that this paper can provide valuable knowledge for researchers to embark into the research of control of CPS.
