某涡扇发动机主燃油通道模糊控制器设计

针对某型涡扇发动机的性能控制,设计了一种可进行多输入选择的开关式双模非对称、非线性段量化因子可自寻优的Fuzzy控制器.其可以在最大和加力状态对发动机状态进行控制,克服了一般模糊控制器因发动机转速动态响应变化快而不能进行实时调整和控制的缺点.该控制器输出与某涡扇发动机电子综合调节器的输出结果的实验比较表明:双模Fuzzy控制器设计简单,有较好的静态、动态特性,与实际输出比较误差较小,且具有很好的非线性校正作用,可作为实际发动机主燃油通道的数字控制器.

Dual-mode Optimization Asymmetry Fuzzy Logic Controller Design for X Aeroengine MFP

In view of the performance control of X Aero engine, a dual-mode optimization asymmetry FLC (fuzzy logic controller) which is switchable, amendable and optional for multi-input is designed. It not only can control the engine at maximum-thrust and afterburner, but also gets over the disadvantage of common fuzzy controllers which cannot do real-time adjustments and control because of the fast dynamic response of the engine rev. Compared with the output of X turbofan engine's EEC (engine electronic controller), the result shows that: this type of FLC is not only simple to design, but also has a good static and dynamic character, a merely small relative error and a good action to nonlinear emendation. So it can be used in the practice of MFP (main fuel passage).
