| 摘 要： | 多项式表示的涡轮发动机平衡流形往往存在偏差，会使辨识的动态参数不太准确。应用样条函数来表示平衡流形展开模型的相应参数，解决了区域内的动、静态参数关系和区域间参数的连续条件构造的辨识问题；以涡喷发动机辨识算例证明了该方法的有效性。

| Abstract: | There were errors in expression of equilibrium manifold with polynomial which could make the dynamic parameters of identification inaccuracy. By applying the corresponding parameters of equilibrium manifold expansion model expressed as the spline functions, the identification problems of the relationship between dynamic and static parameters in zone and the continue conditional construction of interzone parameters were solved. The validation of the method is demonstrated by the identification examples of turbojet engine. |
