主要研究了非线性反演控制规律设计方法在航空发动机控制中的应用.首先基于小偏差线化模型建立了航空发动机的非线性仿射模型,讨论了非线性反演控制规律的设计方法.最后,针对某型涡扇发动机运用非线性反演控制规律设计方法设计了双转子转速控制规律,并给出了仿真结果,仿真结果表明这种控制规律的设计方法在航空发动机控制中是可行的.

The applications of nonlinear backstepping control strategy＇s design method in aeroengine control were analyzed. Firstly,the nonlinear affine dynamic model was established based on small perturbation variable model,and the design method of nonlinear backstepping control strategy was also discussed. Finally, the two-spool speed control rule of some turbofan engine was designed using the nonlinear backstepping control strategy＇s design method. The simulation results show that,the design method is suitable for aeroengine control systems.
