| 摘 要： | 在分析电流变阻尼器工作原理与结构的基础上,基于参考模型设计了1/4车辆悬架系统的滑模控制器.研究了系统在随机路面激励条件下车身加速度、悬架动行程和轮胎动位移等性能指标的控制效果.运用Simu-link在不同的车速和车身质量的情况下进行了仿真分析,结果表明:控制后悬架各性能指标均得到明显改善,滑模控制器性能稳定,对系统参数的改变具有很好的鲁棒性.

| Abstract: | On the basis of the analysis on working principle and structure of electrorheological damper,a sliding mode controller for 1/4 semi-active suspension system of a vehicle is designed based on reference model.The control effects of performance indicators covering body acceleration,suspension dynamic displacement and tire dynamic deflection under random road excitation are studied.A simulation is performed with Simulink under different vehicle speeds and body masses.The results show that all performance indica... |
