| Résumé : | It is generally admitted that the classical conditioning technique is restricted to some application conditions like the bi-property of the controller and its inverse stability. Some extensions to overcome these restrictions are recalled in the paper. The conditioning technique has been conceived and must always be considered as an a posteriori anti-windup method (the a priori knowledge of the non-linearity acting on the desired control variable has not to be known, provided a post-measurement of the actual control variable is available). Hence, this kind of "feedback" anti-windup should always be used because it is never possible to prejudge of any non-linearity that could appear. However, when an a priori knowledge of some non-linearities is available, it is possible to include this knowledge either in the synthesis of the controller or in the design of a "feedforward" anti-windup. Two methods of feedforward anti-windup are given in the paper, namely the optimal conditioning and the predictive conditioning techniques. We propose to keep the term conditioning for these last anti-windup schemes, because as in the classical conditioning technique, we try to "condition" the controller to be able to carry on, as soon as possible, in the same way as in the linear case. © 2000 EUCA. |
