Abstract

We propose a modified model reference adaptive control scheme aimed at improving the transient performance of discrete time adaptive systems while maintaining ideal asymptotic properties possessed by a standard discrete time model reference adaptive control. In the new scheme the estimation error is used directly to modify the underlying controller structure. We show that the modified scheme has essentially the same stability of a standard discrete time model reference adaptive control system but with the transient performance substantially improved. Simulation result has also been presented to illustrate the effectiveness of the proposed scheme
