| 摘 要： | 在电流变液特性试验的基础上,提出基于电流变阻尼悬架的滑模半主动控制。依据滑模控制理论,采用极点配置法确定滑模切换面参数,应用比例切换的控制方法和等速趋近率确定控制律并改善滑模运动的动态品质,同时采用RBF神经网络算法优化滑模控制效果。针对悬架质量参数和车速不确定性,运用MATLAB/SIMULINK进行了悬架半主动控制的建模和仿真分析。仿真结果显示,与被动悬架相比基于RBF神经网络的滑模半主动控制能有效改善悬架性能,对于悬架的不确定性有较好的自适应性。

| Abstract: | On basis of the characteristics testing of electro-rheological fluid,this paper presents semi-active control for suspension based on ER damper.According to sliding mode control theory,the parameters of the switching surface are determined by the method of pole assignment.A proportion switching method and an equal near rate is used to amend the dynamic quality of sliding mode motion in the proposed controller.Meanwhile,the RBF neural network arithmetic is introduced to optimize the sliding mode control resul... |
