An anti-skid braking control method for a civil aircraft comprises the following steps: analyzing the stress condition of an aircraft system by constructing an anti-skid braking model of the civil aircraft and a flight dynamics and kinematics model of the aircraft to obtain corresponding force and torque; a BSMC controller is designed for the anti-skid braking system, the braking force is controlled by controlling the braking coefficient muBragg, and finally control over the anti-skid braking system of the civil aircraft is achieved. The backstepping sliding mode controller (BSMC) is used for controlling the aircraft braking instruction, so that the system is kept at the optimal slip rate in the braking process of the aircraft, the highest braking efficiency is ensured, the abrasion degree of aircraft wheels is reduced, and the loss cost of the aircraft braking system is reduced.
一种民用飞机防滑刹车控制方法,通过构建民用飞机防滑刹车模型以及飞机的飞行动力学与运动学模型,对飞机系统受力情况进行分析,得到对应的力和力矩;针对防滑刹车系统,设计BSMC控制器,控制刹车系数μBrake来控制刹车力,最终实现民用飞机防滑刹车系统的控制。本发明通过反步滑模控制器(BSMC)对飞机刹车指令进行控制,使得飞机在制动过程中,系统保持在最佳滑移率处,保证刹车效率最高,降低飞机机轮的磨损程度,减少飞机刹车系统的损耗成本。
