摘要
研究航空发动机的非线性动态模型的建立问题。利用Volterra级数对航空发动机的动态过程进行描述,建立非线性模型,提出了模型的辨识算法。利用某型涡扇发动机的动态仿真,进行了发动机Volterra模型辨识及验证。结果表明,Volterra模型可以描述发动机从慢车与最大间的动态过程。
Modeling of nonlinearity dynamic respondence of the aero engine was studied.The dynamic process of the aero engine was described by using the Volterra progression model.And identification arithmetic of the Volterra progression model for aero engines was proposed.It was applied to a certain turbofan engine by imitating the dynamic respondence.The Volterra progression model can describe the dynamic process from low to high rotating speed of aeroengine.
