Abstract

A nonlinear robust control-system design framework predicated on a hierarchical stability-based switching controller architecture is developed. Specifically, using equilibria-dependent Lyapunov functions a hierarchical nonlinear robust control strategy is developed that robustly stabilizes a given nonlinear system over a prescribed range of system uncertainty by robustly stabilizing a collection of nonlinear controlled uncertain subsystems
