摘要
在建立主动悬架二自由度动力学模型的基础上,运用最优控制理论求解目标性能函数并进行最优控制器的设计,利用Matlab/Simulink进行了模型建立与仿真分析。仿真结果表明,运用最优控制的主动悬架各项性能对比被动悬架均得到了明显改善。
Based on the two freedom dynamic model of active suspension, an optimal controller was designed by utilizing the method of optimal control theory for solving the objective performance function. The simulation analysis was carried out in the Matlab/simulink. The results of simulation showed that the vibration reduction effect of active suspension was obviously improved compared with the passive suspension.
