汽车防抱死制动系统H_∞控制与PID控制的比较研究

控制方法是汽车防抱死制动系统的核心技术。为了提高ABS系统的鲁棒性能,在建立汽车防抱死制动系统数学模型的基础上,设计了H∞控制器,在Matlab/Simulink平台上对基于H∞控制器的ABS系统进行了动态仿真,并与基于传统PID控制器的ABS系统进行对比。通过对仿真结果进行比较发现,PID控制和H∞控制都能使ABS系统获得较好的制动性能;H∞控制响应迅速、具有优秀的稳定性和鲁棒性,总体控制效果优于PID控制。

Comparative Research of H∞ and PID Control Strategies for Automobile Antilocked Braking System

Control strategy is the core technology of ABS（automobile anti-locked braking system）.To improve the robustness of ABS system,a H∞ controller are designed based on the modeling of ABS. And the dynamic process of ABS based H∞ controller is simulated through Matlab/Simulink.What ＇s more,it＇s process is compared with the ABS system based traditional PID controller. By comparing the simulation results, it shows that both PID and H∞ controller can make ABS braking performance efficient, H∞ control strategy can respond more quickly and has more excellent stability and robustness. Hence, the control performance of H∞ is better than PID.
