基于模糊控制的汽车防抱制动系统仿真

Simulation of ABS Based on Fuzzy Control

汽车防抱制动系统(ABS)通过在制动过程中自动控制车轮的制动力矩从而防止了车轮抱死。这对于提高汽车制动时的方向稳定性和转向操纵性,改善汽车的制动效能,保证驾驶员和乘客的安全是十分重要的。文中通过对某轻型客车的防抱制动过程进行动力学分析,建立了该轻型客车ABS模糊控制系统的数学模型,并且在Matlab/simullnk仿真软件下进行了计算机仿真。仿真结果表明,模糊控制的防抱制动系统能取得较好的控制效果,具有一定的自适应能力。

Anti-lock braking system(ABS) automatically controls the brake torque of each wheel to prevent it from getting locked in the process of braking. This is important to improve the stability, steerablity and brake efficiency of the vehicle during braking and maintain the safety to the driver and passengers. A dynamical analysis of the anti-lock breaking processes of a light bus is carried out in this paper. The mathematical model of the fuzzy control system of anti-lock braking system in this bus is established. In the environment of Matlab/Simulink simulation software, the braking processes of the bus are simulated. The simulation results show that the ABS with fuzzy control is effective in control and self-adaptive to a certain extent.
