A Finite Frequency Method for µ-Analysis
Linköping University, Department of Electrical Engineering, Automatic Control. Linköping University, The Institute of Technology.

Abstract [en]

This paper presents and discusses a method for assuring an upper bound of the structured singular value (µ), by treating the frequency as a real parametric uncertainty on continuous time systems. Using this approach a complete frequency interval can be covered in one µ-computation. By subdividing the frequency range and using a pruning scheme an efficient and accurate method is obtained for computing an upper bound of a dynamic system. The method is composed of existing µ-methods and branch and bound schemes.
