摘要: 研究兼有参数不确定性和非结构不确定性的混合不确定系统的鲁棒稳定性,该问题 可以转化为具有参数摄动的传递函数族的最大H∞范数的计算问题,针对区间对象的加权 H∞范数的最大值问题,给出了精确的计算公式并讨论了顶点检验成立的条件.Abstract: This paper deals with robust stability analysis of systems with both parametric and unstructured uncertainties. This problem can be transformed to the computation problem of the maximal norm of transfer functions with parametric perturbations. In this paper, an exact formula is given to compute the maximal norm of a weighted interval plant and the condition under which vertex results hold is discussed.
