Self-Tuning Output Feedback Stabilization of a Class of Nonlinear Systems

Abstract

We develop a self-tuning output feedback control which globally stabilizes a class of single-input, single-output minimum phase nonlinear systems with known and constant relative degree containing a vector of unknown parameters. The constant parameter vector is not restricted to enter linearly in the state equations but it is assumed to belong to a known compact set and an imprecise knowledge of the nonlinearities (e.g. look up tables) is allowed.
