H_∞ 与 μ 鲁棒控制方法在车辆主动悬挂中的应用

Applications of H ∞ and μ Robust Control Methods in Vehicle Active Suspension

在概述Ｈ∞与μ鲁棒控制的基本理论之后，着重介绍了国外学者应用Ｈ∞方法于车辆（包括磁悬浮列车）主动悬挂的鲁棒控制系统的研究情况。他们的研究结果表明。Ｈ∞方法优于ＬＱＧ方法，是车辆主动悬挂控制的有效方法。应用Ｈ∞和μ方法于铁路车辆主动悬挂控制，是一个具有理论意义与工程价值的研究课题。

In this paper,the basic theory of H ∞ and μ robust control is summarized first.Then the research work of scholors abroad using H ∞ and μ robust control for vehicle (including Maglev) active suspension is introduced.Their research results show that the H ∞ control for vehicle active suspension is better than the LQG optimal control,and is an effective method for active suspension.The application of H ∞ and μ robust control method in railway vehicle active suspension is a research task with both theoretic and engineering significance.
