Communication and computing co-design under imperfect channel conditions for control and scheduling in CPS 2.0

Communication in the cyber-physical system (CPS) is a prerequisite for the computational process. The emerging CPS 2.0 concept necessitates a comprehensive consideration of communication parameters, including communication distance, transmit power, and noise intensity, as well as their impact on the computational process. This chapter mainly focuses on the joint design of communication and computing in CPS, considering factors such as communication delay and packet loss when designing scheduling policies. A single-loop wireless network control CPS is used as the basis for a concise illustration of a comprehensive co-design control. Subsequently, the narrative gradually expands to include multi-loop control systems. Moreover, the age of information was introduced as an indicator to assess the timeliness of the interaction between the CPS and physical devices. This metric possesses characteristics of simplicity and extensibility, and it can be tailored into goal-oriented metrics, enhancing the overall applicability of the methodology presented in this chapter. The scheduling policy and control commands are presented, considering both traditional algorithms and deep reinforcement learning algorithms. These methods can serve as a reference for readers seeking a comprehensive design methodology for CPS co-design.
