The invention relates to a brake control method with brake torque disturbance compensation. The brake control method with the brake torque disturbance compensation function comprises the steps that the current brake pressure value of an airplane is obtained, and a target sliding speed is generated according to the current brake pressure value and runway environment information; acquiring the current speed and the wheel angular speed of the aircraft; inputting the current speed of the airplane, the angular speed of airplane wheels and the current brake pressure value into a linear expansion state observer, generating brake disc torque disturbance data, and adjusting a brake disc pressure-torque conversion coefficient according to the brake torque disturbance data; determining a target brake pressure based on the target slip speed and the brake disc pressure-torque conversion coefficient; and according to the target brake pressure, the airplane wheel angular speed and the airplane deceleration are updated. According to the brake control method and device, disturbance in the pressure-torque conversion coefficient of the brake disc can be compensated in real time, the accuracy of the brake torque is ensured, and therefore the accuracy and reliability of brake control are improved.

    本公开涉及一种具有刹车力矩扰动补偿的刹车控制方法。上述一种具有刹车力矩扰动补偿的刹车控制方法包括:获取飞机当前刹车压力值,并根据当前刹车压力值以及跑道环境信息生成目标滑移速度;获取飞机当前速度和机轮角速度;将飞机当前速度、机轮角速度和当前刹车压力值输入线性扩张状态观测器,生成刹车盘力矩扰动数据,并根据刹车力矩扰动数据调整刹车盘压力‑力矩转换系数;基于目标滑移速度和刹车盘压力‑力矩转换系数确定目标刹车压力;根据目标刹车压力,更新机轮角速度和飞机减速度。本公开能够实时补偿刹车盘压力‑力矩转换系数中的扰动,确保刹车力矩的准确性,从而提高了刹车控制的精准度和可靠性。
