摘要
针对1/2车4自由度汽车震动模型和磁流变阻尼器力学简化模型,提出了汽车半主动悬架系统的自适应Backstepping控制器设计方法。该方法所设计的控制器能自动调节控制器参数,以适应汽车悬架系统中某些参数在一定范围内的变化。仿真结果表明,与被动悬架相比,所设计的控制器不仅增加了悬架系统的快速稳定性,而且汽车的平顺性也得到了明显改善。
Based on the model of half-car four-degree-of-freedom and the simple model of magneto-rheological(MR) fluid damper,an adaptive backstepping control strategy is presented with considering the parameters uncertainty of the suspension system. The controller designed by the strategy can adaptive to the change of system parameters. Simulation results show that the designed controller can greatly improve the stability and the ride comfort of the suspension system.
