Abstract :
The aim of this article is to design an air-fuel ratio control law for a gasoline IC engine. The air-ratio is measured by a lambda sensor in the exhaust manifold. As a consequence, a variable transport delay arises in the model considered. A nonlinear control approach based on a Takagi-Sugeno´s (TS) model of the system is used. A Parallel Distributed Compensation (PDC) control law is then derived taking into account the variable time delay. Finally, some simulations are given to show the efficiency of the developed control law.
