Abstract
A method () for controlling a proportional valve. The method includes the steps of: (i) providing () a proportional flow valve system that includes: a closed loop flow controller () including a proportional flow control valve (), a flow sensor (), and an adjustable gain (); and an adaptive controller () including a model () of the closed loop flow controller, and a gain control (); (ii) actuating () the proportional flow control valve; (iii) measuring () actual gas flow; (iv) determining () a difference between the measured gas flow rate and a desired gas flow rate; (v) adjusting () the proportional flow valve using the determined difference; (vi) initiating () a response from the model of the closed loop flow controller; (vii) determining () a gain for the closed loop flow controller; and (viii) adjusting () the adjustable gain of the closed loop flow controller.
