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 semiactive control vehicle suspension system. Three different strategies are used to compare and verify the validness of semiactive 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 semiactive control device with great potential.
