Robust Control for Linear Systems with Structured Uncertainty

Abstract

The main theme of this research is the robust stabilization of linear uncertain control systems with structured uncertainty, from both the time domain and frequency domain perspectives. First, from an analysis point of view, two new results on improved measures of stability robustness are presented, one from the frequency domain (polynomial) perspective, the other from the state space (matrix theory) perspective. Then design algorithms are presented that completely utilize the structural information of the uncertainty. The frequency domain based design also considers a class of non-minimum phase systems. Finally the aspect of combined structured and unstructured uncertainty is addressed and design methods are presented that treat these two types of uncertainty in a unifying framework. Keywords; Hurwitz invariance, stability robustness, Transfer functions, Polynomials, Parametric analysis.
