Abstract

In some implementations, a controller of a machine may identify an expansion ratio associated with a variable geometry turbocharger (VGT) of the machine. The controller may determine, based on the expansion ratio, wear-reduction information that indicates a force-reduction threshold position of the VGT. The controller may select, based on the wear-reduction information and performance information indicating a desired position of the VGT, an optimized position of the VGT. The controller may cause the VGT to be adjusted to the optimized position. In this way, the controller causes the VGT to operate within a force-related wear-reduction operating range (e.g., that causes the VGT to avoid excessive force being exerted on one or more components of the VGT), which improves a durability of the VGT.
