摘　　要：建立了1/4汽车主动悬架模型,应用最优控制理论进行了汽车主动悬架的LQG控制器的设计,并Matlab/Simulink软件中进行仿真。结果表明:具有LQG控制器的主动悬架对车辆行驶平稳性和乘坐舒适性的改善有良好效果。Through the establishment of quarter vehicle model and the application of optimal control theory, a LQG （Linear Quadratic Gaussian） controller of automobile active suspension was designed. A system simulation model based on Matlab/Simulink environment was built and used for simulation. The simulation results demonstrated that the active suspension with a LQG controller could improve automobile riding comfort performance enormously.
