Robust Adaptive Control of Multivariable Nonlinear Systems

Abstract

Our research is focused on development of reconfigurable robust adaptive control architectures that can be designed with systematic methods to have guaranteed performance specifications and robustness/stability margins. Research in this direction over the past three years has led to a powerful set of tools shaping The Theory of Fast and Robust Adaptation. This new paradigm for design of adaptive control systems embeds the robustness specifications explicitly into the control problem formulation (control objective) and enables one to predict the closed-loop system performance a priori based on the conservative bounds of uncertainty. The time-delay margin of these architectures can be systematically tuned using methods from classical and robust control.
