| 摘 要： | 根据涡轮发动机平衡流形展开模型的特点提出了两步建模方法。将复杂非线性建模转化为静态参数拟合和带约束条件的动态参数最小二乘辨识，根据单轴涡喷发动机气动热力模型辨识算例证明了方法的有效性。

| Abstract: | Modeling method with two step is proposed according to the characteristic of the expansion model. Modeling of nonlinear system is translated to static parameter fitting and dynamic identification with least-square method, and the validation of the method is demonstrated by identification of turbojet engine with one shaft. |

| Keywords: | turbojet engine equilibrium manifold identification least-square |
