Abstract:
1. A method for controlling a diesel engine system, the diesel engine system including a diesel engine having a fuel-side and an air-side, the fuel-side of said diesel engine including at least one fuel injector, the air-side of said diesel engine including an intake manifold, an exhaust manifold, and a turbine adapted to drive a compressor for providing compressed air to the intake manifold, the method comprising the steps of: providing a combined fuel and air-side controller adapted to coordinate both the fuel-side and air-side control of the engine; sensing one or more fuel-side parameters and one or more air-side parameters; and outputting a fuel profile signal and one or more air-side control signals for controlling at least a part of the fuel-side and at least a part of the air-side of the engine; wherein the combined fuel and air-side controller includes a multivariable Model Predictive Controller adapted to compute both the fuel and air-side parameters using a central optimization algorithm or routine.
