Anisotropic Suboptimal Control for Systems with Linear-Fractional Uncertainty

Abstract

The problem of synthesis of robust anisotropic suboptimal controllers is stated and solved for systems with uncertain parameters. This paper considers a general case of unstructured parametric linear-fractional uncertainty bounded in spectral norm. The initial synthesis problem for the uncertain system is embedded into the synthesis problem for some auxiliary system with certain parameters, augmented controlled output, and additional input.
