Abstract :
The idea of improving the transient behaviour in model reference adaptive control by using the estimation error to modify the underlying controller structure has attracted attention in the literature. In this note, we show that the modifications proposed so far can in fact all be derived as linear feedbacks from the tracking error. Consequently, the improved performance obtained with these schemes is solely due to a nonadaptive high gain feedback
