Abstract

This paper presents the L₁ adaptive output feed- back controller for a class of uncertain nonlinear systems in the presence of time and state dependent unknown nonlineari- ties, and multiplicative unmodeled dynamics. The L₁ adaptive controller ensures uniformly bounded transient and asymptotic tracking for system's both signals, input and output, simultane- ously. The performance bounds can be systematically improved by increasing the adaptation rate.
