Torque Control System for Diesel Engine

Free-Piston Diesel Engine Dynamics and Control

Free-piston diesel engines are characterized by freely moving pistons without any rigid crankshaft or camshaft connected to the pistons. This allows a highly compact and e cient engine design, but requires automatic control of the piston motion. This paper present a dynamic mathematical model of a free-piston diesel engine, a control oriented dynamic analysis, and a novel computer-based piston ...

Adaptive Model Predictive Control of Diesel Engine

Sliding Mode Control for Diesel Engine Using Extended State Observer

This paper does a research on turbocharged diesel engines both of air-path or speed-path alone, and proposes a cooperative control strategy of air and speed-path two loop TDE system. For modern diesel engines, accurate air/fuel ratio (AFR) and exhaust gas recirculation (EGR) rates design are very important to meet the requirements of emission standards of NOx and PM. For the EGR and AFR rates a...

Semi-physical mean-value NOx model for diesel engine control

In this paper, a new physics-based model for the prediction of NOx emissions produced by diesel engines is presented. The aim of this work is to provide a Mean-Value Model (MVM) adapted for control design and online estimation. The proposed approach is based on the simplification of a zero-dimensional thermodynamic model. Only the main phenomena taking part in NOx formation are kept and they ar...

Nonlinear control for a diesel engine: A CLF-based approach

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 guarantee...
