Abstract
Systems and methods for use with water-fuel supply to industrial engines are provided. A method for controlling water supplied to an engine may include using both a desired water-fuel ratio, and a compensated fuel flow. This compensated fuel flow may be calculated by a controller-implemented complementary filter, which may include receiving, by the controller, a first signal and a second signal. The complementary filter may subtract the second signal from the first signal to create an error signal, lag the error signal to create a lagged error signal, and add the lagged error signal to the second signal to create a compensated signal. The controller may calculate a water flow request using a desired water-fuel ratio and the compensated signal.
