摘要
文中用所建的1/4车辆模型对采用磁流变阻尼器的半主动悬架实施最优控制进行研究。采用改进型Bouc-W en模型来模拟磁流变阻尼器。利用小种群遗传算法对随机最优控制器的权值进行寻优。仿真结果表明,采用最优控制的磁流变阻尼器半主动悬架性能指标明显优于被动悬架。
Based on a quarter vehicle model built, the implementation of optimal control on semi-active suspension with the magnetorheological （MR） damper is investigated in this paper. The improved Bouc-Wen model is used to simulate the behavior of MR damper. The optimal weight values for the optimal controller are found by using micro-genetic algorithm. Simulation results show that the performance indicators of MR damper-based semi-active suspension with optimal control are obviously superior to that of passive suspension.
