The invention relates to an aircraft anti-skid brake control method based on slip rate control, which is characterized by comprising the following steps of: 1, analyzing the stress of an aircraft wheel in the braking process of an aircraft brake; 2, calculating the aircraft wheel slippage rate s of the aircraft; 3, the braking torque is controlled within the optimal braking torque range based on the slip rate; 4, the specific operation process of the aircraft anti-skid brake control method based on slip rate control is carried out; according to the method, pressure optimization does not depend on skid resistance any more, control over pressure increasing, pressure reducing, pressure maintaining, adjusting, pressure releasing and the like is carried out on the pressure through the current slip rate, it is guaranteed that the brake pressure of the whole brake system is at the optimal point, and therefore the slip frequency can be effectively reduced, and the brake efficiency is improved.
本发明涉及基于滑移率控制的飞机防滑刹车控制方法,其特征在于,所述控制方法,包括:步骤1,飞机刹车制动过程中机轮的受力分析;步骤2,计算飞机的机轮滑移率s;步骤3,基于滑移率将刹车力矩控制在最佳刹车力矩范围内;步骤4,基于滑移率控制的飞机防滑刹车控制方法的具体操作过程;本发明所述方法不再依赖防滑去进行压力寻优,而是通过当前的滑移率对压力进行增压、减压、保压、调整、泄压等控制,去保证整个刹车系统的刹车压力在最优点,所以能够有效的减少打滑的频次,提高刹车效率。
