摘　　要：提出一种基于参考模型的复合模糊控制方法,它把主模糊控制器与基于参考模型的逆模糊控制器进行复合,构成复合模糊控制器,主、逆模糊控制器输出构成合成控制量。并把该方法用于航空发动机控制,通过让被控制量逼近参考模型性能,实现对低压转子转速的无静差控制与基本模糊控制相比,控制性能改善较大,供油量变化物理可实现。仿真结果证明了该方法的有效性。The paper brings forth a reference model based composite fuzzy controller. It consists of main fuzzy controller and reference model based inverse fuzzy controller, and the two controllers construct composite fuzzy controller, and their outputs form composite control varible. The way is applied to aero - engine control By making controlled variable approximate the performance of reference model realize the control without static error on the rotate speed of low - pressure rotor, and in comparisn to general fuzzy control system, the performance improves greatly. The variation of Mf variable can be produced mechanically. The simulation prves the effectiveness of the way.
