1. A gas turbine engine oil flow control system comprising:
a variable flow oil pump structured to generate a pump variable flow of oil during operation of a gas turbine engine;
an oil flow control valve in fluid communication with the variable flow oil pump, the oil flow control valve structured to change the pump variable flow of oil to a valve variable flow of oil through operation of the oil flow control valve;
an oil consumer associated with operation of the gas turbine engine and configured to receive the valve variable flow of oil changed by the oil flow control valve, the oil consumer having a variable consumption demand for delivery of oil; and
an oil flow controller configured to generate a valve command for the oil flow control valve based on the variable consumption demand of the oil consumer.
