Nonlinear control for a diesel engine: A CLF-based approach
Olena Kuzmych, Abdel Aitouche, Ahmed El Hajjaji, Jerome Bosche
Abstract
In this paper, we propose a control Lyapunov function based on a nonlinear controller for a turbocharged diesel engine. A
model-based approach is used which predicts the experimentally observed engine performance for a biodiesel. The basic
idea is to develop an inverse optimal control and to employ a Lyapunov function in order to achieve good performances. The
obtained controller gain guarantees the global convergence of the system and regulates the flows for the variable geometry
turbocharger as well as exhaust gas recirculation systems in order to minimize the NOx emission and the smoke of a biodiesel engine. Simulation of the control performances based on professional software and experimental results show the effectiveness of this approach.
