摘要
通过3自由度车辆半主动悬架系统模型的建立,采用LQG理论确定了半主动悬架的控制方法,并在MatLab/Simulink环境中对其进行仿真,并把它与被动悬架作了比较。仿真结果表明,相对被动悬架,具有LQG控制的半主动悬架在降低人体的加速度、改善车辆的乘坐舒适性和平顺性及行驶安全性上有显著的效果。
Through a 3-DOFs of vehicle model with semi-active suspension,using Linear-Quadratic-Gaussian（LQG） optional regulator theory,it was simulated in the environment of Matlab/Simulink and was compared with the conventional passive suspension. The results demonstrate that the senti-active suspension with LQG controllers has good effect on the aspect of decreasing the body＇s acceleration and improving vehicle＇s riding performances and driving safety.
