Abstract :
This paper presents a novel adaptive control methodology for a class of uncertain nonlinear systems in the presence of unmodelled dynamics. The adaptive controller ensures uniformly bounded transient response for system´s both input and output signals simultaneously. The performance bounds can be systematically improved by increasing the adaptation gain.
