Real and Complex Stability Radii: A Survey,form . → . + .Δ. where ., . are given and Δ is unknown. In this paper we give a survey of the results obtained so far. Although our main reference will be to continuous-time systems we will also present some results for the discrete-time case.

Application of Analytic Centers to Feedback Design for Systems with Uncertainties,ntral solution for general, convex systems of inequalities, we present new algorithms for solving several classes of problems of robust feedback design, providing also new methods for ellipsoidal approximations of the state vector in the case of fixed saturation bounds for the controls and disturbances.

https://doi.org/10.1007/978-3-662-29503-8The paper discusses topologies that naturally arise in the study of robust control problems. A new ‘robust topology’ is defined. It is shown that this topology is Hausdorff.

Gruppierung der Nahrungsmittel,In this work properties of inverse radial matrices and their relations to generalized stability radii are discussed. A characterization of an inverse radial matrix is introduced. The connection between these matrices and the stability radii is presented. The case of equality between the complex and the real stability radii is characterized.

https://doi.org/10.1007/978-3-662-29517-5This note deals with stabilization of parametric families using transfer matrices which are themselves parameterized in the same manner, a problem which is of some interest in the context of indirect adaptive control. It is shown that constancy of the McMillan degree is a necessary condition for stabilizability with arbitrary convergence rates.
