In this paper, an adaptive control method is presented for a class of first
-order systems with nonlinear parameterization. The main features of the sc
heme are that a novel integral-type Lyapunov function is developed for cons
tructing an asymptotically stable adaptive controller, and output tracking
error bounds are provided to evaluate the control performance of the adapti
ve system. The design procedure and the effectiveness of the proposed contr
oller are illustrated through an example study.
