解耦模糊控制方法及在飞控中的应用

A Decoupled Fuzzy Method and Its Application to Flight Control

以某型飞机为对象，控制飞机纵向定高恒速飞行。由于模型是非线性的，采用模糊控制，对具有两个输入两个输出系统的模糊控制方法进行研究，找出了解耦控制规律，并结合PID控制器综合构成了模糊PID控制器。仿真结果显示控制过程时间短，超调量小，振荡小，为飞行控制提供了一种新方法。

In this paper, a decoupled fuzzy method is devoloped for longitudinal flight control. To simplify the nonlinear problem, a new fuzzy approach for TITO system is given and relative tables are demonstrated. To decrease oscillation and overshoot of the responses of velocity and hight of flight, PID control is combined with fuzzy method. Simulations show that this decoupled fuzzy method can given satisfactory results of flight control at given states.
