Five-Full-Block Structured Singular Values of Real Matrices Equal Their Upper Bounds
(2021) In IEEE Control Systems Letters 5(2). p.583-586- Abstract
- We show that the structured singular value of a real matrix with respect to five full complex uncertainty blocks equals its convex upper bound. This is done by formulating the equality conditions as a feasibility SDP and invoking a result on the existence of a low-rank solution. A counterexample is given for the case of six uncertainty blocks. Known results are also revisited using the proposed approach.
