A multivariable control scheme is designed that reduces smoke generation on an experimental marine diesel engine equipped with a variable geometry turbocharger. The variable geometry turbocharger allows the improvement of the steady-state ship hydrodynamic and propulsion characteristics and requires coordination with the injected mass fuel to achieve a good transient performance. The variable geometry turbocharger provides an extra degree of freedom to speed up the air loop dynamics, and consequently, reduce smoke generation without compromising the engine torque response und to improve the steady-state ship speed. The controller achieves satisfactory tradeoffs between the conflicting goals of maneuverability, fuel economy und emissions.
