Problems solved by technology

As a result, traditionally implemented discrete and uncoordinated control methods can sometimes suffer from low accuracy, especially during fast transients
Furthermore, this traditional control method requires extensive calibration activities to ensure an acceptable trade-off between engine performance and pollutant emissions under any operating conditions

Embodiment Construction

[0143] Some embodiments may include such as figure 1 and 2 An automotive system 100 is shown in FIG. 1 , which includes an internal combustion engine (ICE) 100 , such as a compression ignition engine (eg, diesel) or a spark ignition engine (eg, gasoline). The ICE 100 has an engine block 120 defining at least one cylinder 125 having a piston 140 coupled to rotate a crankshaft 145 . Cylinder head 130 cooperates with piston 140 to define combustion chamber 150 . A fuel and air mixture (not shown) is placed in combustion chamber 150 and ignited, resulting in thermally expanding exhaust gases that cause reciprocation of piston 140 . Fuel is provided by at least one fuel injector 160 and air passes through at least one air intake 210 . Fuel is provided to fuel injector 160 at high pressure from fuel rail 170 in fluid communication with high pressure fuel pump 180 which increases the pressure of fuel received from fuel source 190 . Each of cylinders 125 has at least two valves 21...

Abstract

This article discloses a method for controlling the operation of the air boosting system (195) of an internal combustion engine (110). The method includes the steps of: monitoring multiple output parameters of the air boosting system (195); calculating the output parameters of the monitored output parameters. Errors between each of and their target values; apply each of the calculated errors to a linear controller (605, 610, 615) that generates virtual inputs; use the virtual inputs to calculate Multiple input parameters of (195); using each of the input parameters to determine the position of the corresponding actuator (322, 332, 290) of the air boosting system (195); operating based on the determined position of the actuator Each of said actuators (322, 332, 290); wherein the input parameters are calculated with the aid of a non-linear mathematical model of the air boosting system, said model being configured such that each of said virtual inputs Has a linear relationship with only one of the output parameters and vice versa.

Description

technical field [0001] The present disclosure relates to a method of controlling the operation of an air charging system of an internal combustion engine, such as an internal combustion engine of a motor vehicle. Background technique [0002] It is known to equip internal combustion engines with an air charging system for supplying air into the combustion chamber. Air charging systems traditionally include an intake duct that provides air from the ambient environment to an intake manifold that is in fluid communication with each of the combustion chambers through at least one intake port. An intake valve is positioned in the intake duct with an actuator arranged to move the valve member to regulate air flow towards the intake manifold. [0003] The air boost system also includes a turbocharger that forces air into the intake manifold. Turbochargers typically include a compressor rotationally coupled to a turbine, where the compressor is placed in the intake manifold and th...
