Titre : Synthesis of stabilizing antiwindup controllers using piecewise quadratic lyapunov functions Titre original : La synthèse de stabiliser d'anti contrôleurs de remontage employant le lyapunov par morceaux quadratique fonctionne Type de document : texte imprimé Auteurs : Tiwari, Pradeep Y., Auteur ; Mayuresh V. Kothare, Auteur ; Mulder, Eric F., Auteur Article en page(s) : 2341-2345 p. Note générale : Automatique Langues : Anglais (eng) Mots-clés : Actuator  saturation  Antiwindup  Bilinear  matrix  inequalties  (BMI)  Constrained  control  Optimal  control  Piecewise  linear  system  Saturation  de  déclencheur  Anti  remontage  Inequalties  bilinéaires  de  matrice  (BMI)  Commande  contrainte  Commande  optimale  Système  par  morceaux  linéaire Index. décimale : 629.8 Résumé : We consider the problem of antiwindup controller synthesis based on the general antiwindup framework presented in Kothare (Automatica, vol. 30, no. 12, pp. 1869–1883, 1994) applicable to linear time-invariant systems (LTI) subject to a saturating actuator. Our synthesis approach takes advantage of the fact that the antiwindup system is a piecewise affine system and thus, we can utilize piecewise quadratic Lyapunov function theory Johansson and Rantzer (IEEE Trans. Autom. Control, vol. 43, no. 4, pp. 555–559, Apr. 1998), Rantzer and Johansson (IEEE Trans. Autom. Control, vol. 45, no. 4, pp. 629–637, Apr. 2000), and Johansson (Proc. 14th World Congr., Beijing, China, 1999, pp. 521–5260) to determine a stabilizing antiwindup control law. The synthesis problem is expressed in terms of bilinear matrix inequalities (BMIs) and is solved using an iterative approach as well as using commercial software. The performance of the system is optimized by minimizing an upper bound on the induced $L_2$ gain of the system. The proposed approach is demonstrated using examples.
