Abstract
A method of controlling the fuel pressure within a fuel delivery system having a fuel pump that delivers fuel to a fuel rail of an internal combustion engine includes providing a set-point fuel pressure, generating a feed forward signal having a set of fuel pump motor control parameters based upon the set-point fuel pressure and the desired fuel flow rate, providing a pressure sensor to measure the fuel rail pressure, comparing the fuel rail pressure to the set-point fuel pressure and generating an error value based upon the difference between the fuel rail pressure and the set-point fuel pressure, providing a feed back controller adapted to receive the error value and to generate a feed back control signal, combining the feedback control signal and the feed forward control signal to generate a motor controller signal.
