Abstract:
In this article, we present the numerical computations of singular values and lower bounds of structured singular values, known as μ-values, for a family of Discrete Fourier Transform matrices. The μ-value is a well-known mathematical tool in linear control theory which speaks about the stability and instability analysis of feedback systems. The comparison of lower bounds of μ-values with the well-known MATLAB routine mussv is investigated.
