Abstract

This paper describes a comprehensive framework for the development of a model-based robust coordinated control system, which is used to regulate the gas exchange processes of an advanced turbocharged natural gas engine with multifaceted control objectives. The natural gas engine involved in this study features a multi-input, multi-output structure and is highly-nonlinear. A robust coordinated control system is synthesized to realize desired performances of the engine over its entire operating region and is compared to a benchmark production control system in simulation. The comparison results explore the merits of coordinated control over decoupled control in the aspect of complex engine dynamics.
