    摘要: Various systems and methods for controlling a turbocharger of an engine via a wastegate are described. In one example, actuation of the wastegate is limited when outside a range, the limits of the range varying with boost pressure, turbine inlet pressure, turbine outlet pressure, and atmospheric pressure. In this manner, a tracking error may be reduced when controlling the boost pressure and using the boost pressure to actuate the wastegate in a boost-based wastegate configuration.
