摘要
根据汽车系统动力学原理及牛顿力学定律建立了转向工况下的半主动悬架整车数学模型,并将模糊规则控制与传统PID控制相结合,设计了基于可调阻尼减振器的汽车半主动悬架模糊PID控制器。运用Matlab7.0/Simulink6.0软件对此控制系统进行了仿真计算,结果表明,该控制器有效改善了汽车在转向工况下的动态性能,保持了良好的车身姿态,提高了乘坐舒适性。
A complete vehicle mathematics model of semi-active suspension system is established in the steering situation based on the principle of vehicle dynamics and Newton＇s Law of Mechanics,and the semi-active suspension fuzzy PID controller based on adjustable damping shock absorber is designed by combining fuzzy control with conventional PID control.The control system is simulated on software Matlab7.0/Simulink6.0,and the simulation results show that the controller can improve the vehicle dynamic performance,keep good vehicle body attitude and improve the ride comfort in the steering situation.
