  • Abstract
    A redesign of model reference adaptive control is proposed using a non-quadratic Lyapunov function to derive a new adaptive law. For systems with relative degree one such a redesign ensures a tracking error which belongs to L1+α. A choice of 0<α<1 leads to a generically faster convergence of the tracking error to zero than the standard adaptive law with α=1. Simulations indicate that such a redesign improves system tracking performance.
