摘要
对汽车的主动悬挂系统和被动悬挂系统的特点进行了分析对比,并以主动悬挂系统为研究对象,建立了基于1/4车辆动力学模型,应用最优控制理论进行了二次型最优控制器设计,并用MATLAB/SIMULINK软件进行1/4车辆悬挂系统仿真分析,仿真结果表明,采用最优控制方法的主动悬挂系统可以较好地改善车辆行驶的平顺性和乘坐舒适性。
It instroduces the merits,the work principal and different characteristics about passive suspension and active suspention,illustrates how to use optional control theory to design a controlling method for automotive active suspension and how to use MATLAB/SIMULINK software to perform 1/4 vechicle simulasion analysis.The simulation results show that the designed active suspension with optional controller can improve driving vehicle smoothness and comfort.
