### Abstract

An upper bound for the complex structured singular value related to a linear time-invariant system over all frequencies is given. It is in the form of the spectral radius of the H_{∞}-norm matrix of SISO input-output channels of the system when uncertainty blocks are SISO. In the case of MIMO uncertainty blocks the upper bound is the _{∞}-norm of a special non-negative matrix derived from H_{∞}-norms of SISO channels of the system. The upper bound is fit into the inequality relation between the results of μ and ℓ_{1} robustness tests.

N2 - An upper bound for the complex structured singular value related to a linear time-invariant system over all frequencies is given. It is in the form of the spectral radius of the H∞-norm matrix of SISO input-output channels of the system when uncertainty blocks are SISO. In the case of MIMO uncertainty blocks the upper bound is the ∞-norm of a special non-negative matrix derived from H∞-norms of SISO channels of the system. The upper bound is fit into the inequality relation between the results of μ and ℓ1 robustness tests.
