  • 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 nonlinearities, and multiplicative unmodeled dynamics. The L1 adaptive controller ensures uniformly bounded transient and asymptotic tracking for system´s both signals, input and output, simultaneously. The performance bounds can be systematically improved by increasing the adaptation rate.
