为提高航空发动机某工作点的模型精度，并拓宽航空发动机在该工作点控制包线的范围，可应用非线性模型来描述该工作点的动态过程。基于该非线性模型，首先应用Lyapunov稳定性定理设计出一组控制器，然后应用广义Gronwall-Bellman引理的方法完成该控制器性能验证。仿真研究表明：系统响应速度快，能有效抑制干扰，具有良好的跟踪性和鲁棒性，验证了该设计方法的有效性。

In order to improve the model accuracy of the aero-engine in an operating point and extend the control envelope around the operating point, one strategy can be sought to apply nonlinear model to describe the dynamic characteristics. Firstly, a nonlinear controller can be obtained for the aero-engine using Lyapu-nov stability theorem. Then Generalized Gronwall-Bellman lemma is used to validate the controller perfor-mance. Finally, the simulation study shows that the proposed design can provide fast transient response, good tracking performance and robustness, and reject the disturbance effectively to validate the effective-ness of the control design approach.
