Abstract
A turbocharger control system including a turbocharger having an exhaust turbine and a centrifugal compressor mechanically coupled by a shaft, a pressure sensor for detecting a boost pressure, an electric motor configured to apply a rotational pressure to the shaft in response to a current, and a processor determining an expected rotational speed in response to the boost pressure, determining a current value in response to a difference between the expected rotational speed and a desired rotational speed, and generating a control signal indicative of the current value to control the current applied to the electric motor.
