Abstract

Systems and methods for use with water-fuel supply to industrial engines are provided. A method for controlling water supplied to an engine (12) 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 (19), which may include receiving, by the controller (18), a first signal (42) and a second signal (44). The complementary filter (19) may subtract the second signal (44) from the first signal (42) to create an error signal (58), lag the error signal (58) to create a lagged error signal (60), and add the lagged error signal (60) to the second signal (44) to create a compensated signal (62). The controller (18) may calculate a water flow request using a desired water-fuel ratio and the compensated signal (62).
