Singular-value and eigenvalue techniques in the analysis of systems with structured perturbations. (English) Zbl 0577.93052
Techniques are presented for assessing the stability of linear multivariable unity feedback systems with structured perturbations in the plant, i.e. each element of the perturbation matrix has an upper bound on its absolute value. In particular, these procedures can be applied to systems which have diagonal, block-diagonal, or other block structured perturbations.
