Abstract :
A new adaptive parameter update law is proposed for discrete-time model reference adaptive control to ensure robustness with respect to l 1+α (1≤α<∞) parameter variations and disturbances in the sense that all closed-loop signals are bounded and the tracking error belongs to l 1+α (α≤α~<∞) and converges to zero asymptotically.
