Abstract
Systems and methods are disclosed to control a braking system. One method provides a command signal to a valve to control fluid pressure to a wheel brake in a braking system, includes determining a pressure signal based on a first set for control gains and a pressure command signal, determining a first current signal based upon the pressure command signal, subtracting an actual pressure signal from the pressure command signal to produce an error signal, and determining a second current signal based on the second set of control gains and the error signal. The method further includes subtracting a supply pressure actual signal from a supply pressure nominal signal to produce a pressure differential signal, multiplying the pressure differential signal by a selected gain to produce a third current signal, and summing the first current signal, the second current signal and the third current signal to produce an output signal.
