论文摘要
高性能实时无线连接是工业互联网（IIOT）的核心。实现无线闭环控制对于各种关键任务IIT系统至关重要。现有的无线技术无法满足闭环控制的严格性能要求。本文提出了一种新颖的无线解决方案，称为\ textsf {gallop}，用于实现对多跳或单跳网络的闭环控制。 \ textsf {gallop}采用了一种务实的设计方法来应对无线闭环控制的挑战。 \ textsf {gallop}的关键设计方面包括用于循环交换的控制 - 感知双向调度，基于合作的多用户多样性以及可扩展操作的低空信号传导，可稳固的重新启动技术。 \ textsf {gallop}专门为控制循环而设计的，这些控制循环在整个网络上封闭，动力学以几毫秒为单位。基于蓝牙5测试床上的广泛系统级模拟和硬件实现的性能评估表明，\ textsf {gallop}提供了具有非常低和确定性的延迟，非常高的可靠性和高可伸缩性，可满足Versatile Iiot Iiot应用程序的无线闭合控制的严格要求。
High-performance real-time wireless connectivity is at the heart of the Industrial Internet-of-Things (IIoT). Realizing wireless closed-loop control is crucial for various mission-critical IIoT systems. Existing wireless technologies fall short of meeting the stringent performance requirements of closed-loop control. This paper presents a novel wireless solution, called \textsf{GALLOP}, for realizing closed-loop control over multi-hop or single-hop networks. \textsf{GALLOP} adopts a pragmatic design approach for addressing the challenges of wireless closed-loop control. Key design aspects of \textsf{GALLOP} include control-aware bi-directional scheduling for cyclic exchange, robust retransmission techniques based on cooperative multi-user diversity and low-overhead signaling for scalable operation. \textsf{GALLOP} has been specifically designed for control loops that are closed over the whole network with dynamics on the order of few milliseconds. Performance evaluation based on extensive system-level simulations and hardware implementation on a Bluetooth 5 testbed demonstrates that \textsf{GALLOP} provides high-performance connectivity with very low and deterministic latency, very high reliability and high scalability, to meet the stringent requirements of wireless closed-loop control for versatile IIoT applications.
