摘　　要：为了提高汽车的乘坐舒适性和驾驶稳定性,在建立二自由度1/4整车悬架系统模型的基础上,利用最优控制极小值原理,设计线性二次型最优状态控制器.最后利用MATLAB对主动悬架系统和被动悬架系统进行仿真.实验结果表明:线性二次最优控制的可行性和优越性.In order to improve maneuverable stability and ride comfort of an automobile, based on the established quarter suspension automobile model of two degree-freedom, the linear quadratic optimal state controller was de- signed by the optimal control of minimum principle. Finally the active suspension system and the passive suspen- sion system were simulated by MATLAB. Through the result, the feasibility and advantages are demonstrated in the linear quadratic ootimal control theory.
