Abstract:
In this paper, we propose a robustness measure for LTI systems with
causal, nonlinear diagonal perturbations with finite L_2-gain. We
propose an algorithm to reliably compute this quantity. We show how
to find a state-feedback controller that achieves the global maximum of
the robustness measure.
