Research on modelling and simulation for aircraft anti-skid braking

In this paper, the ground maneuver of aircraft anti-skid braking is studied using co-simulation method, which joints the software MSC.ADAMS/Aircraft with MATLAB/Simulink. A virtual prototype of aircraft is established in the multibody system dynamics software MSC.ADAMS/Aircraft. The anti-skid braking control model, which adopts the multi-threshold PID control method with a slip-velocity-controlled, pressure-bias-modulated (PBM) system, is established in MATLAB/Simulink. The ADAMS model is then connected to block diagrams of the anti-skid braking control model in MATLAB/Simulink, so that the ground maneuver of aircraft anti-skid braking is simulated. Results are presented to investigate the performance of anti-skid braking system and responses of aircraft induced by braking. The brake system has good control effect on braking the aircraft, but its performance gets down in low speed stage, which brings on serious skid.
