Abstract :
Robustness and performances in the presence of disturbances of an indirect adaptive control scheme driven by the prediction error which is designed by organizing a sliding mode are examined in this paper. A new idea for performance improvement in the presence of disturbances is presented. The idea is applied to plants with unknown relative degree. It is proved that the proposed scheme can provide arbitrarily improved transient performances. The results are confirmed by simulation
