Abstract
This paper presents an adaptive control methodology for a class of systems in the presence of unknown time- varying parameters, time-varying disturbances and unmodeled actuator dynamics. The 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 speed of adaptation.
