Abstract

Various methods for compensating a deflected linkage in a wastegate arrangement are provided. In one example, current is applied to an actuator to move a wastegate valve coupled through a linkage to the actuator for diverting gasses from a turbocharger. The position of the actuator is indicated, and a correction to said indicated actuator position is applied compensating for deflection of the linkage based at least on said applied current. Said applied current is adjusted when said corrected actuator position reaches a position corresponding to a desired valve position.
