Abstract: An internal combustion engine operatively coupled with a variable load and an electronic control system operatively coupled with the internal combustion engine. The electronic control system is structured to receive an engine speed target value, a first engine speed feedback value, and a second engine speed feedback value. The electronic control system processes the first engine speed feedback value and the second engine speed feedback value to determine a feedforward correction value. The feedforward correction value is determined to correct for first variation between the second engine speed feedback value and the first engine speed feedback value due to variation in the variable load and to distinguish between the first variation and a second variation due to operation of the internal combustion engine. The control system processes the first engine speed feedback value target, the second engine speed feedback value and the feedforward correction value to determine an engine fueling command, and controls fueling of the internal combustion engine using the fueling command.
