Network and Control Co-Design in Cyber-Physical Systems

Abstract

Cyber-Physical System (CPS), which is used in various fields, has received increasing attention. Since the advent of Industry 4.0, CPS has been actively studied in fields such as smart factories and vehicle networks. CPS is tight integration of cyber space and physical space through networking. Therefore, the design of a network that connects cyber space and physical space takes a large portion in the importance of CPS research. As CPS can be expressed in various types of systems, it is necessary to design various networks accordingly. This dissertation focuses on the wireless networked control system among CPS. However, there are various types of wireless networked control system, and since the network and physical systems in wireless network control system are mutually interacted, a network and control co-design is required, not network design. In this dissertation, we propose the network and control co-design of CPS that considers the following three situations: (i) wireless channel uncertainty, (ii) heterogeneous sampling rates, and (iii) hierarchical networked control system.
