The Performance of Automobile Antilock Brake System Based on Fuzzy Robust Control

摘要

Aiming at the characteristics of automobile braking and the performance demands of ABS, the mathematic model is founded. ABS control strategy based on robust and fuzzy logic hybrid control is advanced. The fuzzy and robust control simulation model is founded with Matlab/Simulink for automobile ABS. The model has better robustness, good steady state characteristics, strong anti-interference ability and high control accuracy. The simulation results compare with a single robust control, fuzzy control and the ideal ABS control. The results show the fuzzy robust control strategy can effectively improve the response of automobile ABS, strengthen the vehicle's ability to adapt to various roads. It also can get the best braking slip ratio and the braking distance.
