Direct adaptive fuzzy control for a class of discrete-time systems

Abstract

A direct adaptive control scheme is presented for a class of discrete-time nonlinear systems. The control scheme is based on an online functional approximation approach which modifies a standard or Takai-Sugeno (1985) fuzzy control system. A modified version of the standard key technical lemma which allows for adaptive systems with dead zones is used to guarantee asymptotic convergence of the tracking error to an /spl epsiv/-neighborhood of zero.
