Abstract
An engine control system for an engine that drives a generator includes a temperature sensor that generates a temperature signal and a control module that determines a generator torque based on an engine speed and a generator characteristic. The control module determines a torque correction factor based on the temperature signal and determines a corrected generator torque based on the generator torque and the torque correction factor. Various embodiments of the invention utilize engine speed, system voltages field winding duty cycle engine temperature, ambient temperature and/or generator current.
