摘要提出了一种分析主动悬架系统鲁棒性能的系统方法。首先，简要介绍了H-μ控制方法的背景知识。其次，给出了主动悬架结构不确定性的计算公式，并讨论了传递函数矩阵的最大奇异值与结构奇异值之间的差别。然后分析了主动悬架系统在假设参数变化的情况下的鲁棒性能。并以某铁路车辆横向主动悬架系统为例，说明了整个设计步骤。
Abstract This paper presents a systematic approach for robust performance analysis of active suspension system. Firstly, the background information on H - μ control methods is briefly described. Secondly, the formula of the structured uncertainties of active suspension are given, and the difference between the maximum singular values and structured singular values of a transfer function matrix is discussed. Then the robust performance of an active suspension system in the presence of assumed parameter variation is analyzed. All the steps are illustrated by means of a numerical example of a railway car with lateral active suspension system.
