Abstract

This paper provides a novel method to improve the transient performance of the model reference adaptive control (MRAC) system. In this proposed framework, a new compensator constructed using the known dynamics is employed to reshape the reference model. Then to retain the closed-loop system stability, a modified adaptive law is provided to diminish the disparity between the modified reference model and the original reference model. Through this modification, the norm bound of the tracking error can be reduced via rigorous theoretical analysis. A wing-rock aircraft is used as the simulation example to verify the effectiveness of the proposed control strategy. It is shown in simulations that the high-frequency components in the tracking error and control signals can be diminished, and the improved transient response of the proposed control can be achieved in comparison to the standard MRAC.
