A METHOD OF FUZZY CONTROL FOR HIGH ANGLE -OF - ATTACK FLIGHT

提出了一种飞机大仰角飞行的动态逆模糊集成控制方法。首先使用动态逆方法求得系统的逆,使系统反馈线性化,然后,用具有在线规则自调整的模糊控制方法来确保系统的最终特性。该方法应用在高性能飞机的俯仰机动指令系统的设计中,仿真结果表明,所设计的控制器满足操纵品质的要求,并且,在大仰角飞行时具有较好的鲁棒性。

This paper presents a dynamic inversion control method for high angle - of - attack flight. First, the aircraft dynamics is inverted to linearize the system dynamics. System performance is guaranteed by using fuzzy control method of. on -line self-tuning rules. The method is applied to design of pitch dynamic command system of a high - performance aircraft. Simulations demonstrate that the controller satisfies handling quality requirements, and exhibits excellent robustness over high angle -of-attack.
