时域中系统鲁棒稳定性的定量计算

本文定量地考虑了当系统参数受到干扰时的稳定性问题。目的为对以状态空间法表示的线性系统鲁棒稳定性的定量计算提出一个统一的结论。文中首先对摄动的分类及对用李亚普诺夫理论求解受扰系统鲁棒稳定性的历史结果进行了述评,进而对其摄动的允许界限的计算提出了新方法。实例表明所示结果较少保守性。

A data model for regions with indeterminate boundaries

Most of spatial phenomena like natural vegetation units and land use areas constantly change over time and have uncertainty spatial extents. Till now, a considerable number of data models have been proposed for spatial objects with sharp boundaries as well as with indeterminate boundaries. However, they mainly concern space and time or space and fuzziness and not yet integrate them into a single unified framework. This paper introduces a formal definition of the conceptual fuzzy spatiotemporal data model, called FSTDM for fuzzy regions based on fuzzy set theory. We also contribute a method of manipulating queries with the presence of both temporal predicate and fuzzy spatial predicate in the condition clause efficiently. We then implement a prototype system.Through the experimental results, we prove that our work can be used to build a specialized system such as GIS, spatial database, and so on.
