1. A method of maintaining a first flow rate through a first valve in a fluid delivery system, the fluid delivery system including a pump and a plurality of fluid valves in fluid communication with the pump, and a controller controlling the pressure generated by the pump and the position of the plurality of valves, the method comprising:
providing the first flow rate of a fluid pressurized by the pump through the first valve;
receiving at the controller a request for a second flow rate of the fluid through a second valve;
determining with the controller a predicted effect on the first flow rate based on the request;
adjusting at least one of the position of the first valve and the pressure generated by the pump to maintain the first flow rate based on the predicted effect; and
adjusting the position of the second valve to provide the second flow rate of the fluid through the second valve.
