This integrative systems proposal focuses on the integration of networked control and wireless communication technologies for real-time, remote monitoring and control. Advancement in wireless sensing and networking have provided convenient and flexible information delivery, and it can also extend our control scope by expanding our space accessibility, thus empowering control systems toward challenging applications in hospitals, robotics control, and manufacturing plants, etc. Driven by real-world demands, many of these applications are characterized by timing constraints that must be satisfied for proper operation, i.e., quick response to external events. Moreover, for remote control, task directives are sensitive in that any alteration or damage will induce erroneous actions, decisions, and even widespread destruction. Thus, the contradiction of random network delay and time-sensitive commands, and open fields and sensitive data transmission makes wireless network-based control systems significantly challenging.Intellectual Merit: This research plan concerns not only the development of data-sensitive control systems, it also studies the design of transport algorithms and computing models which play an important role in facilitating real-time control based on wireless sensing and networking. By integrating a middleware-based approach to compensate for random network delay, we will apply our solutions to time-sensitive, feedback control systems in a case study for motion tracking and control. Broader Impacts: The results of such a wireless network-based control system, which integrates multidisciplinary characteristics, will be used to reveal great potential for industrial electronics, health care, and robotics, and will make a significant impact on people's daily lives. This work will also be used as an experimental concentration for innovative curriculum design of intelligent control. Research and educational results will be broadly disseminated and made available to the public by being posted on the Internet in a timely manner.

该综合系统方案侧重于网络控制和无线通信技术的集成，以实现实时、远程监控和控制。无线传感和网络的进步提供了方便和灵活的信息传递，它还可以通过扩展我们的空间可访问性来扩展我们的控制范围，从而使控制系统能够在医院，机器人控制和制造工厂等具有挑战性的应用中发挥作用。在现实需求的驱动下，这些应用程序中的许多都具有时间限制的特征，必须满足这些时间限制才能进行正确的操作，即对外部事件的快速响应。此外，对于远程控制，任务指令是敏感的，因为任何更改或损坏都会导致错误的行动、决策，甚至广泛的破坏。因此，随机网络延迟和时间敏感命令的矛盾，以及开放领域和敏感数据传输的矛盾给基于无线网络的控制系统带来了极大的挑战。智力优势：本研究计划不仅关注数据敏感控制系统的开发，还研究传输算法和计算模型的设计，这些算法和计算模型在促进基于无线传感和网络的实时控制方面发挥重要作用。通过集成基于中间件的方法来补偿随机网络延迟，我们将在运动跟踪和控制的案例研究中将我们的解决方案应用于时间敏感的反馈控制系统。更广泛的影响：这种基于无线网络的控制系统集成了多学科特点，将显示工业电子、医疗保健和机器人技术的巨大潜力，并将对人们的日常生活产生重大影响。本工作也将作为智能控制创新课程设计的实验重点。研究和教育成果将广泛传播，并及时在互联网上公布给公众。
