摘要

采用磁流变阻尼器实现车辆悬架系统半主动控制.为了便于比较,研究了三种控制策略.提出一种基于最优控制理论的半主动控制方案,给出了悬架系统在B级公路路面激励下控制数值仿真结果.结果表明,基于最优控制理论的半主动控制磁流变阻尼器有明显的控制效果,具有良好的应用前景.
Magnetorheological (MR) damper, which can provide controllable damping forces with very little energy consumption, is proposed to be used in semiactive control vehicle suspension system. Three different strategies are used to compare and verify the validness of semiactive control suspension system, and a strategy based on optimal control theory is proposed and recommended. Road excitation of B level is utilized in numerical simulation. Numerical results presented here demonstrate that the strategy based on optimal control theory is very effective. Furthermore, MR damper is a ideal semiactive control device with great potential.
