On Modifying Model-Reference Adaptive-Control Schemes for Performance Improvement
The idea of improving the transient behavior in model reference adaptive control by using the estimation error to modify the underlying controller structure has recently attracted some attention in the literature. In this note, we show that the modifications proposed so far can in fact all be derived as a linear feedback from the tracking error. Consequently, the improved performance obtained with such a scheme is solely due to a nonadaptive high gain feedback.
