Abstract
The author both reviews some existing stability robustness measures for linear-quadratic (LQ)-optimal systems in the presence of unstructured additive perturbations in the closed-loop system and also derives some new measures. Bounds on the perturbation matrix which preserve the stability of the closed-loop system are presented. Both time and frequency domain results are presented. A numerical example is given
