摘要：

In this note, the adaptive control problem is considered for a class of nonlinearly parametrized systems. By introducing a novel kind of Lyapunov functions, a direct adaptive controller is developed for achieving asymptotic tracking control. The transient performance of the resulting closed-loop system can be guaranteed by suitably choosing the Lyapunov function to construct the controller. The effectiveness of the proposed scheme is illustrated with two examples. (C) 1999 Elsevier Science Ltd. All rights reserved.
