控制软件分析,第一部分开环特性

Control software analysis, Part I Open-loop properties

Eric Feron, Fernando Alegre

摘要:

随着数字世界进一步进入日常生活,人们对实时软件与物理设备的交互所带来的日益严峻的挑战提出了质疑。在医疗系统、运输系统或武器系统等不同领域遇到的许多事故和事件最终都归因于“软件故障”。由于与物理系统交互的实时软件也可以被称为控制软件,因此由于实时软件故障而导致的长时间的事故可能被视为控制系统工程的机会。在本文中,我们只感兴趣的运行时的错误,这些软件是一个直接实现的控制系统规范:对于定义良好,理解良好的控制体系结构,如目前在数字控制系统的标准教科书,理论计算机科学的现状是装备精良,足以解决和分析控制算法。看来,这些分析的一个核心要素是李雅普诺夫稳定性理论,在计算机实现中转化为不变理论。

英文摘要:

As the digital world enters further into everyday life, questions are raised about the increasing challenges brought by the interaction of real-time software with physical devices. Many accidents and incidents encountered in areas as diverse as medical systems, transportation systems or weapon systems are ultimately attributed to "software failures". Since real-time software that interacts with physical systems might as well be called control software, the long litany of accidents due to real-time software failures might be taken as an equally long list of opportunities for control systems engineering. In this paper, we are interested only in run-time errors in those pieces of software that are a direct implementation of control system specifications: For well-defined and well-understood control architectures such as those present in standard textbooks on digital control systems, the current state of theoretical computer science is well-equipped enough to address and analyze control algorithms. It appears that a central element to these analyses is Lyapunov stability theory, which translate into invariant theory in computer implementations.
