Résumé :

This paper presents an approach to modeling and controlling discrete-time non-linear dynamical system on the basis of a finite amount of input/output observations. The controller consists of a multiple-step-ahead direct adaptive controller which, at each time step, first performs a forward simulation of the closed-loop system and then makes an adaptation of the parameters of the controller. This procedure requires a sufficiently accurate model of the process in order to meet the control requirements. Takagi-Sugeno fuzzy systems and Lazy Learning are two approaches which have been proposed in control literature as effective ways of identifying a plant. This paper compares these two approaches in two main configurations: (i) when the number of observations is fixed and (ii) when new observations are collected on-line after each control action. Simulation examples of the control of the manifold pressure of a car engine are given. © 2002 Published by Elsevier Science B.V.
