修正因子法模糊控制在航空发动机中的应用

The application of fuzzy control based on modifying factors in aero-engine

针对航空发动机复杂多变、非线性的控制要求,采用一种基于修正因子模糊控制方法设计控制器,并对航空发动机的基本发动机控制模型进行仿真实验。仿真结果表明:基于修正因子模糊控制方法设计的控制器具有超调量小、上升时间和调节时间短的特点;与传统的PID控制方法相比较,可以达到更好的控制效果。

A new method of fuzzy control based on modifying factors is applied for the design of the controller of aero engine according to the demand of complex,variable and nonlinear control. The result of simulation on basic aero engine control model indicated that this kind of fuzzy control method have the characteristics of small overshoot,short rise time and adjustment time. Compared with traditional PID control methods ,it can get better control performance and fulfill the need of complex control of modern aero engine.
