系统不确定性是控制系统分析和设计中必须考虑的。H∞和μ方法是系统鲁捧性分析和设计的一类新的有效工具。本文在给出了 H∞和μ方法的基本概念后,通过把一些实际问题转化成 H∞控制问题和μ分析问题,对利用 H∞方法进行系统设计以及利用μ方法进行系统分析作了说明,并提供了一些主要结果,最后讨论了使用 H∞方法的μ综合问题。 System uncertainty is a must in control system analysis and design. The H∞ and μ methods are a new class of effective tools for system robustness analysis and design. After giving the basic concepts of H∞ and μ methods, this paper introduces some practical problems into H∞ control problems and μ analysis problems, explains the system design using H∞ method and the system analysis using μ method, Some main results are provided. Finally, the μ synthesis problem using H∞ method is discussed.
