Abstract
A machine includes a VGT and a controller. The controller monitors, based on causing the VGT to operate according to the non-dynamic control scheme, a plurality of hardware limit parameters associated with an engine of the machine. The controller determines that a hardware limit parameter, of the plurality of hardware limit parameters, satisfies a dynamic threshold for the hardware limit parameter and thereby causes the VGT to operate according to a dynamic control scheme. The controller then monitors the plurality of hardware limit parameters and thereby determines that each hardware limit parameter, of the plurality of hardware limit parameters, satisfies a non-dynamic threshold for the hardware limit parameter. The controller therefore causes the VGT to operate again according to the non-dynamic control scheme.
