Abstract
Various methods for controlling a wastegate with an actuator having a temperature-dependent magnetic field are provided. In one example, the magnetic field is estimated based on operating conditions and other parameters, and used to apply a magnetic correction to a voltage supplied to the actuator. The methods may provide accurate wastegate control in the presence of varying magnetic fields, ensuring the proper supply of boost to an engine.
