The invention discloses an anti-skid braking system based on a self-adaptive reference speed module and a control method. Dividing the aircraft speed into a high section, a middle section and a low section through an adaptive reference speed module, calculating the deceleration rate of the aircraft at the same time, calculating the corresponding reference speed deceleration rate according to the deceleration rate of the aircraft, the aircraft speed and the wheel speed, and outputting the reference speed at the next moment; as the reference speed reduction rate in the method is jointly determined according to the runway state, the airplane speed and the airplane wheel speed, it can be ensured that the slippage rate of the airplane wheels relative to the airplane is kept within the optimal slippage rate range, the ground combining torque is utilized to the maximum extent, the braking efficiency is improved, and the braking distance is reduced.

    一种基于自适应参考速度模块的防滑刹车系统及控制方法。通过自适应参考速度模块将飞机速度分为高、中、低三段,同时计算飞机减速率,依据飞机减速率、飞机速度以及机轮速度,计算相应的参考速度减速率,输出下一时刻的参考速度,由于该方法中的参考速度减速率是依据跑道状态、飞机速度以及机轮速度共同决定的,能够确保机轮相对于飞机的滑移率保持在最佳滑移率范围,最大限度的利用地面结合力矩,提高了刹车效率,减少了刹车距离。
