ABSTRACT:
A system and method for controlling a flow of a fluid using a multi-mode control algorithm is described. One embodiment includes a method for changing the multi-mode control algorithm from a closed-loop mode to an open-loop mode. The method includes receiving at least one sensor indicator generated by a sensor. The multi-mode control algorithm is modified from the closed-loop mode to the open-loop mode when, based on the at least one sensor indicator, the threshold condition is satisfied. The multi-mode control algorithm is used by a flow controller to control a flow of a fluid according to a set point.
