Abstract
An indirect adaptive control for a discrete-time non-linear system tha t is fully input-output linearizable is developed. The unknown paramet ers of the system are identified by using a multi-output RLS algorithm . Based on the certainty equivalence principle, the estimated paramete rs are then utilized in the controller design. Stability of the adapti vely controlled closed-loop system is shown by using the Lyapunov meth od. Numerical simulations are included to illustrated the performance of the proposed strategy.
