本文旨在开发一种适用于航空发动机的非线性控制技术。提出了近似非线性模型并给出了合理的辨识程序。在此模型上可以轻松执行精确的输入输出反馈线性化。导出的控制器可以近似线性化对象，使得闭环系统在本地表现出线性输入输出动态。建模和控制通过小型涡轮风扇发动机进行了例证和验证。仿真结果表明，建模精度良好，实现了线性闭环系统动力学。
This paper aims to develop an applicable nonlinear control technique for aeroengines. An approximate nonlinear model is presented and a rational identification procedure is given. Exact input-output feedback linearization can be easily performed on this model. The controller derived can approximately linearize the plant such that the close-loop system exhibits linear input-output dynamics locally. Modeling and controlling are exemplified and validated by a small turbofan engine. Simulation results illustrate that the modeling accuracy is good and linear close-loop system dynamics are achieved.
