N2 - The pressure-bias-modulated (PBM) is an aircraft antiskid brake algorithm with great engineering application. Its control structure is simple, with few debugging parameters, and it is reliable to prevent the wheel from slipping. But the core parameter (reference deceleration rate) lacks adaptability to different runway. Aircraft tend to skid and anti-skid frequently under adverse conditions (wet and icy), resulting in inefficient braking. In this paper, the brake pressure is used to explore the runway conditions, and extended braking stiffness (XBS) is used to adjust the reference deceleration rate. The reference deceleration rate modified with runway exploration will replace the preset reference deceleration rate in the classic PBM algorithm. This gives the PBM algorithm the ability to identify runways. We established a single-wheel aircraft braking system model under simulation conditions, and verified the control algorithm under different runway conditions and time-varying braking torque disturbances. Compared with the classic PBM, the improved algorithm not only effectively reduces the number of wheel slips, but also improves the braking efficiency.
