Nonlinear Model Predictive Controller Design for Air System Control of Variable Geometry Turbocharged Diesel Engine

Improved Controller Design for Turbocharged Diesel Engine

Turbocharged diesel engines are now being used in every automobile by a lot of automobile manufacturing companies. A turbocharged diesel engine (TDE) equipped with variable geometry turbocharger and exchange gas recirculation is explained in detail. A linear turbocharged diesel engine model is presented and its control techniques are explained in detail. Controllers are designed using the linea...

Neural networks for real-time nonlinear control of a variable geometry turbocharged diesel engine

New engines are submitted to emission standards that are becoming more and more restrictive. Diesel engines are typically equipped with variable geometry turbo-compressor, exhaust gas recirculation system, high-pressure common rail system and post-treatment devices in order to meet these legislative requirements. Consequently, the control of diesel engines becomes a very difficult task involvin...

Control of variable geometry turbocharged diesel engines for reduced emissions

A multivariable control scheme is designed to minimize emission of nitrogen oxides NOx and generation of smoke in a Diesel engine equipped with a variable geometry tur bocharger VGT and an external exhaust gas recirculation system EGR Steady state optimization results in operat ing points where NOx emissions and smoke generation are highly coupled and require joint management by VGT and EGR act...

Air-Path Model Predictive Control of a Heavy-Duty Diesel Engine with Variable Valve Actuation

In this paper, a model-based strategy for the air-path, fuel injection timing, and fuel pressure control of a heavy-duty Diesel engine is presented. The engine system is a six-cylinder Diesel engine, equipped with a dual-stage fixed geometry turbo system and a variable valve actuation (VVA) system. The VVA operates on the intake valves, and realizes a late Miller combustion cycle. The control s...
