Stability Radii for Innnite Dimensional Systems with Stochastic Uncertainty
نویسنده
چکیده
We consider linear deterministic systems on real Hilbert spaces which are subjected to a nite number (N) of stochastic, structured, Lipschitzian perturbations. A stability radius is deened and is completely characterized via an N-parameter minimization of the norm of a family of bounded operators. This is in contrast to the determin-istic case where the stability radius is determined by the-function and the corresponding N-parameter optimisa-tion only yields an upper bound.

On Stability Radii of Innnite Dimensional Time{varying Discrete Time Systems
This note introduces a stability radius for discrete time linear time-varying systems on Banach spaces under structured time-varying perturbations of multi{output feedback type. We derive counterparts to some results established for time-varying and/or innnite dimensional diierentiable systems in 3], 6].
متن کاملStability radii of infinite-dimensional positive systems
We show that for innnite-dimensional discrete-time positive systems the complex and real stability radius coincide. Furthermore, we provide a simple formula for the complex stability radius of positive systems by the associated transfer function. We illustrate our results with an example dealing with a simple type of diierential-diierence equations. 1. Introductory remarks This work is motivate...
متن کاملFuzzy Lyapunov stability and exponential stability in control systems
Fuzzy control systems have had various applications in a wide range of science and engineering in recent years. Since an unstable control system is typically useless and potentially dangerous, stability is the most important requirement for any control system (including fuzzy control system). Conceptually, there are two types of stability for control systems: Lyapunov stability (a special case ...
متن کاملStability radii of discrete-time stochastic systems with respect to blockdiagonal perturbations
We consider stochastic discrete-time systems with multiplicative noise which are controlled by dynamic output feedback and subjected to blockdiagonal stochastic parameter perturbations. Stability radii for these systems are characterized via scaling techniques and it is shown that for real data, the real and the complex stability radii coincide. In a second part of the paper we investigate the ...
متن کاملStability Radii of Systems with Stochastic Uncertainty and Their Optimization by Output Feedback
We consider linear plants controlled by dynamic output feedback which are subjected to blockdiagonal stochastic parameter perturbations. The stability radii of these systems are characterized and it is shown that, for real data, the real and the complex stability radii coincide. A corresponding result does not hold in the deterministic case, even for perturbations of single output feedback type...
