摘要

本研究的目的是探讨系统和控制的数值方法的发展,以保证精度。这种研究的最终产物是一种可以在以下意义上被描述为“绝对可靠”的算法:用户将先验地指定所需的最小公差,计算机将提供保证准确到指定公差的答案。虽然这是计算机科学[5]中的一个既定主题,以及科学和工程中的一些应用领域(参见[1,第三部分]),但在控制系统领域,这个方向似乎是相当新的。以前工作的一个特点是使用计算机代数工具和避免浮点运算。

Validated numerical methods for systems and control engineering
The aim of this research is to investigate the development of numerical methods for systems and control which have a guarantee on accuracy. An end-product of such research is an algorithm which could be described as "infallible" in the following sense: the user would specify a priori a tolerance as small as desired, and the computer would provide an answer which was guaranteed to be accurate to the specified tolerance. Though this is an established subject within Computer Science [5], as well as a few application areas in science and engineering (see [1, Part III]), the direction appears to be quite new in the control systems area. A characteristic feature of previous work is the application of computer algebra tools and the avoidance of floating-point arithmetic.
