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.

Lemmon MichaelCCR-0208537“网络控制系统中基于性能的软实时调度“该项目正在开发高性能网络控制系统设计的新方法。所考虑的网络控制系统将控制器功能分布在通过自组织通信网络进行通信的微控制器的集合上。该项目使用软变化的（m，k）-坚定的保证模型来表征任务调度网络控制系统。该项目包括三项任务。第一个任务获得上界的辍学概率，确保闭环系统的鲁棒性能。这些边界定义了软（m，k）模型，这是研究的重点之一。第二个重点是可实现的嵌入式系统的设计，执行软（m，k）模型所产生的控制design.The项目的更广泛的影响是通过列入本项目中开发的方法和概念，在本科课程，介绍嵌入式系统的原则。
