模糊控制在四轮牵引力控制系统中的应用

针对四轮驱动汽车,应用模糊理论设计了牵引力控制系统的油门控制器和制动控制器。建立了基于Matlab/Simulink的硬件在环开发平台,并选择分离路面和棋盘路面两种工况进行了硬件在环试验。结果表明,所设计的控制器能有效地消除驱动轮过度滑转,从而提高了车辆的牵引性能,且在路面条件突变时具有较强的适应性。

Applications of Fuzzy Control on Four-Wheel Traction Control System

Fuzzy theory was used to design throttle controller and braking controller of traction control system for four-wheel drive vehicles. A hardware-in-the-loop simulator was built based on Matlab/Simulink, and several tests were processed on split-μ road and chess road. The results show that the controllers can estimate excessive slippage of driven wheel so as to improve traction ability of vehicles effectively, and they are adaptable when road conditions change suddenly.
