摘要
目前对飞机地面偏航运动研究不足。此外,在精确建立飞机地面滑跑模型的同时考虑左右主机轮所处不同路面状况时的飞机地面方向控制有一定难度。针对飞机地面滑跑时的偏航现象,在考虑飞机整体,机轮轮胎,路面状况等特性的情况下,研究了基于在线插值模糊控制的飞机地面方向综合控制方法。建立了三点式起落架布局的飞机地面航向非线性动力学模型。采用在线插值模糊控制方法,综合利用方向舵控制系统、前轮转弯控制系统和防滑刹车控制系统对飞机地面滑跑时的航向进行纠偏。仿真表明,在飞机的左右主机轮处于不同路面状况下时,该综合控制方法可以在不增加控制器复杂程度前提下,提高控制效率,对飞机航向进行有效纠偏。
At present,the study on the problem of the airplane yawing on the runway is not enough.Besides,it is difficult when establishing accurate model of an airplane and considering the main wheels being in the different ground conditions at the same time.To solve the yawing problem of airplanes taxing on the runway,an integrated ground directional control system based on interpolation on-line fuzzy control is studied,taking into account the characteristics of the airplane＇s body,tires and ground conditions.Aimed at the airplane with three-wheel undercarriage,the non-linear dynamic model of an airplane running on the runway is established.The direction of the airplane running on the runway is controlled by the integrated system of the rudder control system,the nose wheel steering control system and the aircraft antiskid braking control system,adopting the method of interpolation on-line fuzzy control.Confirmed by simulation,the new controller can avoid the quantization error of the traditional fuzzy controller and correct the yaw angel of the airplane on the ground effectively without adding any complexity.
