SUPERVISORY CONTROL OF A COMPRESSION IGNITION ENGINE

摘要

A system for controlling the combustion behavior of an engine is provided. The engine is equipped with a plurality of control subsystems that influence combustion in the engine. The system includes a controller configured to receive a plurality of inputs, to determine a desired subsystem states to operate the engine, and to determine a target value for each of a plurality of control parameters, wherein the target values for one or more control parameters depends on the values of the plurality of inputs. The controller is further configured to communicate the target values of control parameters to the control subsystems.

1. An engine control system comprising a supervisory controller, a fuel control system, and a charge air control system, the supervisory controller configured to:
receive a set of inputs, said inputs comprising feedback values of one or more combustion parameters, driver inputs, target values for one or more combustion parameters, steady state control targets, and actual engine states; determine a target engine indicated torque; determine a target charge air pressure, a target charge air temperature, and a target charge air oxygen content based on the target engine torque and engine speed; calculate a target compensated charge air pressure, a target compensated charge air temperature, and a target compensated charge air oxygen content based on the received inputs; determine target values for one or more fuel control parameters; communicate the target fuel control parameters to the fuel control system; communicate the target compensated charge air pressure, the target compensated charge air temperature, and the target compensated charge air oxygen content to the charge air control system.
