Abstract
A system for monitoring and controlling flow rate of a fluid through a valve, the system including a flow rate sensor configured to measure the flow rate of the fluid through the valve, and a controller in communication with the flow rate sensor. The controller is configured to receive the measured flow rate from the flow rate sensor and determine if the measured flow rate is equal to a predetermined flow rate value. In response to determining equality, the controller is configured to determine a minimum valve position threshold (x), and determine a minimum flow rate threshold (y) corresponding to x. The controller is further configured to calculate a corrected flow rate (ŷ) using x, y, and an indication of valve position (v). Additionally, the controller is configured to control a valve operation using the corrected flow rate (ŷ).
