Abstract
An apparatus for controlling an air system of a diesel engine in a steady state. The air system comprises a waste gas recycling system and a turbocharging system. The apparatus comprises: a working condition acquisition device, configured to acquire a parameter for indicating an practical working condition of a diesel engine; a decoupling calculation device (), coupled to the working condition acquisition device, and configured to, according to the parameter from the working condition acquisition device and a transfer function characterizing the diesel engine, calculate a decoupling transfer function, the transfer function being calibrated based on working condition data of the diesel engine in a steady working zone thereof; an air system parameter processing device (), coupled to the working condition acquisition device, and configured to process a parameter for indicating a state of the air system; and a signal generation device (), coupled to the decoupling calculation device and the air system parameter processing device, and configured to, according to the decoupling transfer function from the decoupling computation device and a processing result from the air system parameter processing device, generate a first drive signal for the waste gas recycling system and a second drive signal used for the turbocharging system.
