随着信息技术的发展，未来的控制系统需要成百到数千的传感器和制动器进行低延迟，高可靠性连接，以保持系统运行的稳定。目前采用的有线连接方式会引起许多机械问题，未来需要将有线转移到无线进行连接。然而现有的无线通信系统一般被设计为了提高系统的吞吐率或者降低功耗，因而无法达到控制系统毫秒级低延迟的可靠传输需要。本课题旨在通过科学的方法研究可用于系统以及更多智能控制系统的共性问题，建立最差时延时间的理论模型，设计物理层和介质访问控制层，通过由一个固定的初始传输时间表、在最差情况下预估足够的时间以重新传输和利用非常低速率编码以在编码开销和重新传输次数之间取得最佳平衡，预期在慢衰减环境中满足毫秒级的延迟和高可靠性要求。并进行相关芯片的流片验证。为未来的大集群的智能控制系统应用奠定基础。

With the development of information technology，hundreds or thousands of sensors and actuators in future control systems need low-latency, high reliability communication in order to keep system stable. Currently, costly wired communication consistent dominant and easy to cause many mechanical issues, which will be replaced by wireless technique in the near future. However, the existing wireless communication system is generally designed to improve the system throughput or reduce power consumption, and therefore cannot reach the latency of millisecond under condition of high reliability. This project aims to study the common problems of intelligent control system through the scientific method, research on building the theoretical model of worst case latency, design the MAC layer and physical layer jointly. The system can evaluate enough time to retransmission or trade-off between ECC overhead and the times of retransmission, as a result, it can achieve the requirement of low-latency and high reliability in slow fading environment. We want to tape out associated ASIC design, which will also lay the foundation for application in large cluster of intelligent control systems.
