On the basis of analyzing the principium of anti-skid braking system, in order to overcome the negative effects of structure parameters changes and uncertainties,avoid the system error of the model and difficulties of modeling ,the control scheme based on fuzzy control for anti-skid braking system is proposed. By utilizing fuzzy logic toolbox of MATLAB , fuzzy control scheme is achieved. Furthermore, the whole system model is built in virtue of MALAB/SIMULINK toolbox, the performance of fuzzy control scheme is simulated for various road conditions, then simulation curves are offered. Simulation results show that the control scheme proposed earns big benefits from improving the brakeing performance and raising the brakeing efficiency.
