Abstract

An electronic controller for a sub-system of an air management system including an area conversion module and a sub-system area control module. The area conversion module includes inputs for a bleed output pressure set point, a bleed output pressure measurement, a sub-system parameter set point, a sub-system parameter measurement, and a sub-system output pressure measurement; and sub-modules for calculating an area set point and an area measurement. The sub-modules generate the area set point as a function of the engine bleed output pressure set point, the sub-system parameter set point, and the sub-system output pressure measurement; and the area measurement as a function of the bleed output pressure measurement, the sub-system parameter measurement, and the sub-system output pressure measurement. The sub-system area control module generates a control output for the sub-system as a function of the calculated area set point and the calculated area measurement.
