According to aircraft braking system design requirement and system characteristic, a aircraft automatic braking system whole frame was proposed. Taken automatic braking control logic of RTO state for example, control logic was designed, control logic model was set up and simulated using Statelfow, the simulation results show the correction of the control logic. The automatic braking system hardware-in-loop simulation was established. Through a given reduction rate of 3m/s2, the digital simulation and hardware-in-loop simulation were processed, results show that the taxiing distance of digital simulation was 672m, of hardware-in-loop simulation was 1016m, reduction rate changed between 2.88~3.07 m/s2, meet the requirment of system design, and its correctness and rationality is veriifed.
