1 Introduction
Etxebarria [A] has presented a simple adaptive control
scheme for discrete systems using two linear two-layered
works. Specifically, one of works is
used to learn online the dynamics of the unknown plant
using the Widrow-Hoff delta rule. The work
uses this learning to adjust its connection weights and to
generate the control signal. Etxebarria has proven that
the resulting closed-loop system is globally stable and has
shown that the controlled output tracks the reference 3 Proposed method for enhanced transient
