Integrated Communication, Sensing, Computing, and Control for Industrial Power Protection Systems: Analysis and Performance Optimization

With the continuous advancement of industrial automation technology, industrial power security systems are playing an increasingly important role in ensuring production stability and improving efficiency. This paper studies an industrial power security system that integrates sensing, communication, computation, and control (ISCC), focusing on the performance optimization issues related to latency and reliability. Addressing the trade-offs between latency and reliability across the four components of sensing, communication, computation, and control, and assuming no errors in sensing, closed-form expressions for the maximum latency of the communication-sensing-computation-control system and the maximum packet loss probability of communication are derived. By optimizing the optimal control law and the system’s uplink and downlink bandwidth under constraints of communication rate, maximum available bandwidth, and power, the control cost of the system is minimized. To further enhance system performance, this paper proposes a joint optimization method aimed at simultaneously optimizing the control law and uplink-downlink bandwidth allocation to minimize the system’s control cost.
