ON THE IMPROVEMENT OF THE ADAPTATION TRANSIENTS IN ADAPTIVE CONTROL

Abstract

Abstract A technique to improve the adaptation transient in discrete time Model Reference Adaptive Control (MRAC) systems is given on the basis of applying classical optimization techniques to an equivalent near-linear system to the whole adaptive scheme. The resulting optimization is finally translated into modifications of one of the parameters entering the adaptation algorithm. This allows to compute “a posteriori” values of the adaptive controller parameters previously to the generation of the input to the plant.
