Title: "Collaborative Research: SoD-TEAM: A Feedback-Based Architecture for Highly Reliable Embedded Software"The focus of this project is on developing a theory and architectural framework for incorporating feedback control as a main principle of software engineering. This proposal develops scientific foundations, tools, and architectural design principles to improve the reliability and reduce the development cost of mission-critical software. Two common approaches to ensure reliable system behavior are: 1) Scientific foundations, tools, and architectural principles for ensuring elimination of errors, and 2) foundations, tools, and architectural principles for ensuring tolerance to such errors. While the first solution is sufficient, building completely error-free large-scale systems has been an elusive exercise as evidenced by experiences with today's engineering artifacts (e.g., recalls on vehicles, cascading power blackouts, etc). Consequently, a new approach to robust software design, development and certification is needed that addresses the increasing cost and safety implications of the current practices. Feedback control has proven to be a very successful tool for ensuring correct behavior of complex, poorly modeled systems in the presence of uncertainty. This project applies principles of feedback control and stability envelopes to the engineering of software systems.Program Manager: Anita J. La SalleDate:

标题：“协作研究：SoD-Team：一种基于反馈的高可靠嵌入式软件体系结构”本项目的重点是开发一种将反馈控制作为软件工程的主要原则的理论和体系结构框架。该提案开发了科学的基础、工具和体系结构设计原则，以提高任务关键型软件的可靠性并降低开发成本。确保可靠系统行为的两种常见方法是：1)用于确保消除错误的科学基础、工具和体系结构原则，以及2)用于确保对此类错误的容忍度的基础、工具和体系结构原则。虽然第一个解决方案已经足够，但构建完全无错误的大规模系统一直是一项难以捉摸的练习，这从当今工程制品的经验中得到了证明(例如，车辆召回、级联停电等)。因此，需要一种新的方法来进行可靠的软件设计、开发和认证，以解决当前做法日益增加的成本和安全影响。反馈控制已被证明是一种非常成功的工具，可以确保在存在不确定性的情况下，复杂的、建模不佳的系统的正确行为。本项目将反馈控制和稳定性包络原理应用到软件系统工程中。项目经理：Anita J.La SalleDate：
