摘要
在磁流变减振器外特性分析基础上,设计了1/4车辆的自适应模糊控制器,提出了把1/4车辆模型的半主动控制算法应用于汽车左右前悬架独立控制的策略,并在Matlab平台上进行了仿真。选用国产某型号微型车作为试验车辆,将其被动的左右前悬架改装成磁流变半主动悬架,在多种条件下进行了实车道路试验。试验结果与仿真吻合,表明对左右前悬架进行独立半主动控制是可行的,明显提高了汽车行驶的平顺性。
MR fluid damper's semi-active characteristics were analyzed, a control strategy was studied in which a quarter-vehicle control was used independently to two front MR suspensions of the vehicle. A quarter-vehicle self-adapted logic controller was adopted. The completed system was simulated via SIMU-LINK Toolbox of MATLAB 6.1. One automobile, which was equipped with MR semi-active suspensions instead of front passive ones, was tested in road. Test results tally with simulation ones. It indicates that using semi-active control independently in left and right suspension is feasible. Both MR suspension systems with semi-active logic controller can effectively improve ride comfort of automobile.
