Performance Based Soft Real-time Scheduling in Networked Control Systems

网络控制系统中基于性能的软实时调度这个项目正在开发设计高性能网络控制系统的新方法。考虑中的网络控制系统将控制器功能分布在一组微控制器上，这些微控制器通过自组织通信网络进行通信。该项目使用(m,k)-firm保证模型的软变体来表征网络控制系统中的任务调度。该项目包括三个任务。第一项任务是求出保证闭环系统鲁棒性能的丢失概率上界。这些边界定义了软（m,k）模型，这是研究的一个主要重点。第二个重点是可实现调度器的设计，该调度器执行由控制设计产生的软（m,k）模型。通过将该项目开发的方法和概念纳入介绍嵌入式系统原理的本科课程，可以实现该项目更广泛的影响。

Lemmon MichaelCCR-0208537"Performance Based Soft Real-time Scheduling in Networked Control Systems"This project is developing novel methods for the design of high performance networked control systems. The networked control system under consideration distributes controller functionality over a collection of micro-controllers that communicate over an ad-hoc communication network. The project uses a soft variation of the (m,k)-firm guarantee model to characterize task scheduling in networked control systems. The project consists of three tasks. The first task obtains upper bounds on dropout probabilities that assure robust performance of the closed loop system. These bounds define the soft (m,k)-model, which is one major emphasis of the research. The second emphasis is on the design of implementable schedulers that enforce the soft (m,k) model arising from the control design.The project's broader impact is achieved through the inclusion of methods and concepts developed in this project in undergraduate courses that introduce embedded system principles.
