Appropriate circuitry and electrical connections condition the generator to work in tandem with any other power sources present, while providing electrical power with properties required to safely power the controls.

Abstract: Techniques for learning endstop position(s) of an actuator for a wastegate valve include detecting a learn condition and, in response to detecting the learn condition, performing a learn procedure for the actuator endstop position(s). The learn procedure includes commanding the actuator to a desired position past the endstop position corresponding to a fully-closed wastegate valve while rate-limiting a velocity of the actuator. When the difference reaches its maximum allowed value and the velocity falls below a fraction of its rate limit, the endstop position is learned. When the wastegate valve is requested open, the actuator is then controlled using the learned endstop position. Reference stiffness for a fully-closed wastegate valve could be obtained, and subsequent stiffness checks could then be periodically performed and, if less than the reference stiffness, a duty cycle of the actuator could be increased during open-loop control.
