Embodiment Construction

[0012] Referring to the drawings, wherein like reference numerals denote like parts, figure 1 Engine assembly 10 is schematically illustrated. Engine assembly 10 may be part of device 12 . Device 12 may be a mobile platform such as, but not limited to, a standard passenger car, sport utility vehicle, light truck, heavy duty vehicle, ATV, minivan, bus, mass transit vehicle, bicycle, robot, agricultural implement, sports related equipment, vessel, aircraft, train or any other means of transport. Apparatus 12 may take many different forms and contain multiple and / or alternative components and facilities.

[0013] see figure 1 , the assembly 10 includes the engine 14 . In the illustrated embodiment, engine 14 is an internal combustion engine capable of combusting an air-fuel mixture to produce output torque. However, engine 14 may be any type of engine known to those skilled in the art. see figure 1 , the engine assembly 10 includes a control module 100 operatively connecte...

Abstract

An engine assembly includes a control module configured to receive a torque request and an engine configured to generate an output torque in response to the torque request. The control module includes a processor and tangible, non-transitory memory on which are recorded instructions for performing the method of supervisory model predictive control. The control module includes a multi-layer structure with an upper level ("UL") optimizer module configured to optimize at least one system level objective and a lower level ("LL") trace control module configured to maintain at least one trace parameter. The multi-layer structure is characterized by a decoupled cost function such that the UL optimizer module minimizes the upper layer cost function (CF UL ), and the LL tracking control module minimizes the lower layer cost function (CF LL ). The system level goal may include minimizing fuel consumption of the engine, and the tracking parameters may include delivering requested torque to the engine.

Description

technical field [0001] The present disclosure relates generally to an engine assembly and, more particularly, to supervisory model predictive control in an engine assembly. Background technique [0002] Many modern engines are equipped with multiple actuators to achieve multiple goals, such as better fuel economy and others. However, due to the growing complexity of engine systems, optimizing multiple objectives becomes more challenging. Contents of the invention [0003] An engine assembly includes a control module configured to receive a torque request and an engine configured to generate an output torque in response to the torque request. The control module includes a processor and tangible non-transitory memory on which are recorded instructions for performing the method of supervisory model predictive control. The control module comprises a multi-layer structure, wherein an upper layer (referred to herein as "UL") optimizer module is configured to optimize at least ...
