１引言目前常用的结构奇异值综合算法仍是Ｄ－Ｋ交替寻优算法［２］和μ－Ｋ交替寻优算法［３］，但这两种算法计算繁复，得到的控制器阶数也较高，造成数值计算上的困难，使结构奇异值理论难以为工程应用所接受．因此，研究便于工程应用的μ综合方法是μ理论的一个重要课... 1 INTRODUCTION The commonly used structural singular value synthesis algorithm is still D-K alternating optimization algorithm [2] and μ-K alternating optimization algorithm [3]. However, these two algorithms are complex and the order of controller is also more than High, resulting in numerical computational difficulties, so that the structure of singular value theory is difficult to accept for engineering applications. Therefore, the μ integrated method to study the application of engineering is an important part of μ theory.
