摘　　要：对汽车空气悬架系统的模糊控制方法进行了仿真研究。以1/4车辆模型为仿真对象,建立模糊控制器,并模拟B级路面为随机输入,对模型进行了计算机仿真。结果表明,在引入模糊控制方法后,车辆的行驶平顺性得到了有效改善。另外,当系统模型的结构参数发生改变时,该控制器表现出良好的鲁棒性。Simulation study on the fuzzy control of automotive air suspension systems is carried out.With the quar-ter model as the simulation object,the fuzzy controller is created and simulation is carried out with the sim ulated B-class road profile as the random input.It is shown by the results that the ride is improved evidently with the fuzzy control method introduced.Furthermore,when the system structure parameters varied,the controller shows good ro bustness.
