摘要

摘要: 为了综合体现汽车车身的垂直跳动、俯仰变化以及侧倾问题,建立了七自由度半主动悬架非线性动力学模型和四轮随机路面模型,并加入了制动模块和转向模块。采用改进型Bouc-wen模型来模拟磁流变阻尼器。利用Fuzzy-PID复合控制技术,即利用模糊规则实现了对PID参数的在线修改,使控制器能按操作者最初设定的规则进行自动调整,以便获得更好的控制性能。仿真结果表明:与常规PID控制相比,Fuzzy-PID控制具有更好的控制效果,不仅能够更有效的降低车身加速度、侧倾角加速度与俯仰角加速度,而且能较大的改善悬架动扰度,提高车辆的舒适性和安全性。

Abstract: In order to comprehensively reflect the vertical jump,pitch change and roll motion problems of car body,the nonlinear dynamical model of semi-active suspension with seven degrees of freedom and the random road model of four wheels are established,And the brake model and the steering model are added,using an improved Bouc-Wen model of magnetorheological damper. The Fuzzy-PID compound control technology is used,namely using fuzzy control rules to realize the online modification of PID parameters and make the controller automatically adjust according to the initial rules,so that it could have a better control performance. The simulation results show that,compared with the conventional PID control,the fuzzy-PID has a better control effects and can effectively reduce body acceleration,roll acceleration and pitch acceleration,and it greatly improves the suspension dynamic deflection and raises the comfort and safety of the car.
