โœฆ Synopsis

This paper focuses on analysis of the robustness of full state feedback controlled systems with parametric uncertainties. Both the ability to remain stable and to maintain a prescribed level of performance are assessed. Robustness bounds are developed for a given closed-loop system; these describe the largest magnitude of uncertainty for which the system can both be guaranteed to remain stable and to satisfy a given performance criterion. Furthermore, a maximal robustness bound is developed for a given system that is independent of the choice of controller, but guarantees that for admissible uncertainties, a controller can be found that will satisfy stability and performance criteria. This robustness analysis technique enables the trade-off between performance and robustness to be quantitatively assessed.

For linear systems involving uncertain parameters with known, constant nominal values and uncertain perturbations that vary sinusoidally with time, Lyapunov robustness anslysis is used to determine a stability bound, or margin, for the amplitudes of the parameter perturbations. This bound is the siz

We derive bounds on the parameters of systems represented by a transfer functions such that a system satisfying these bounds will satisfy a bound on the H -norm of the uncertainty in a given nominal system. We develop the bound and give examples for illustration.
