Research and Application for Hydraulic Pressure Anti-lock Brake System Based on Fuzzy PID Control
Contraposing the current application of Anti-lock brake system in hydraulic pressure brake system, a new control strategy is brought forward. The brake characteristics of hydraulic pressure system and instantaneous dynamics of wheels are analyzed. On the base of relevant math model, simulation models are upbuilt by making use of MATLAB/SIMULINK. In order to keep yarage and improve brake efficiency, and considering the nonlinearity, time variant and uncertainty of ABS, the fuzzy control theoretics is adopted. For the shortage of single fuzzy controller, the fuzzy PID controller is designed. The fuzzy controller is optimized by traditional PID controller because of its better control precision. Simulation results indicated that the fuzzy PID controller gets the wheels obtain perfect circumrotate state in brake process all the time, ensures the vehicle having preferable direction maneuverability, stability, and also shorten the brake distance comparatively.
