摘要
对采用模糊控制的汽车半主动空气悬架系统进行了仿真研究。建立了1/4车辆二自由度动力学模型并以其为仿真对象,设计了模糊控制器,以B级路面作为随机输入,进行了计算机仿真分析。仿真结果表明,在采用模糊控制方法后,车辆悬架可以很好地降低簧载质量的垂直加速度,从而使车辆行驶的平顺性和乘坐舒适性得到了提高。
In this paper,simulation study on the control of Semi-active Air Suspension systems is carried out. This paper establish a 1/4 vehicle 2 degrees dynamics model;with this model as the simulation object,the fuzzy controller is designed ;take B-class road noise as the random input ; computer simulation study is carried out. The results of the simulation showed that with the fuzzy eontroller the suspension can evidently reduce the vehicle＇s vibration and improve the ride comfort characteristics.
