摘要
通过建立1／4车辆模型,应用最优控制理论进行了车辆主动悬架的LQG(Linear Quadratic Gaussian)控制器的设计,并在Matlab／Simulink环境中建立系统模型并进行仿真,将仿真结果与被动悬架仿真结果进行对比分析。仿真结果表明,具有LQG控制器的主动悬架对车辆行驶平顺性和乘坐舒适性的改善有良好的效果。
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.Simulation results was compared with passive suspension.The simulation results demonstrated that the active suspension with a LQG controller could improve automobile riding comfort performance enormously.
