| 摘 要： | 研究了动态建模中的模型分析与简化的方法,提出了用可行域范围内的一组离散线性化模型来反映非线性模型,从而可利用线性系统理论对模型进行分析的思想。以微型燃气轮机为对象深入阐述了模态分析方法及其在模型降阶中的应用,并得到可反应大范围负荷变化的动态特性的一组传递函数。图2表2参4

| Abstract: | Ways of modeling analysis and order reduction in dynamic modeling have been studied with suggestions of how to express non-linear models by dispersed linear equations within possible operating ranges, and herewith perform model analysis by making use of the theory of linear systems. Taking micro gas turbines as the object to be dealt with, the art of modeling analysis and its application in models' order reduction is being delineated. A set of transfer functions, that may reflect the dynamic behavior within large load variation ranges, are moreover obtained. Figs 2, tables 2 and refs 4. |
