摘要
本文采用两自由度悬挂系统模型,以目标函数为双加权,通过在线递推计算车身动位移,估计道路的随机统计特性。用三级阻尼器实行半主动悬架的最优控制。
In this paper a two freedom vehicle suspension model is used,and the double weighted objective function is selected.The vehicle dynamic deflection is obtained by the computer on line,and the results are used to estimate the statistical property of road random exciting.The optimal control for the semi active suspension with tri grade adjustable damper is realized.The results show that the property of suspension system is improved greatly.
