Abstract

In this paper, a linear fractional transformation (LFT) approach is proposed in order to design a linear parameter-varying discrete-time $Mathematical equation: $H_\infty $$ controller including an anti-windup compensation. The provided methodology is applied to the control of diesel engine common rail injection systems. Simulation results on a non linear model are then shown and discussed. The control method is brie?y compared with the on-board gain-scheduled PID controller.

Résumé

Dans cet article, une approche LFT est proposée pour concevoir un contrôleur $Mathematical equation: $H_\infty $$ LPV à temps-discret incluant une compensation anti-saturation. Cette méthodologie est appliquée au système d'injection "Common Rail” des moteurs Diesel à injection directe. L'eficacité de ce contrôleur est mise en avant en le comparant à l'aide de simulations avec un régulateur de type PID à gain séquencé embarqué sur véhicule.
