A robust adaptive law for l1-α modeling errors

摘要

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 l1+αˉ (α⩽αˉ<∞) and converges to zero asymptotically
