METHOD AND SYSTEM FOR CONTROLLING A FLOW RATIO CONTROLLER USING FEED-FORWARD ADJUSTMENT
First Claim
1. A method comprising:
- determining a plurality of initial setpoint commands, each of the plurality of initial setpoint commands corresponding to one of a plurality of valves;
sending each of the plurality of initial setpoint commands to a corresponding one of the plurality of valves;
monitoring the plurality of valves for a flow condition requiring an adjustment;
upon detecting the flow condition, predicting the adjustment based on previous setpoints;
determining, by a processing device, a plurality of updated setpoint commands, each of the plurality of updated setpoint commands corresponding to one of the plurality of valves, based on the predicted adjustment; and
sending each of the plurality of updated setpoint commands to the corresponding one of the plurality of valves.

Abstract
A processing device determines a plurality of initial flow setpoint commands, each of the plurality of setpoint commands corresponding to one of a plurality of valves, and sends each of the plurality of initial setpoint commands to a corresponding one of the plurality of valves. The processing device monitors the plurality of valves for a flow condition requiring and adjustment. Upon detecting the flow condition, the processing device predicts the adjustment based on previous setpoints, and determines a plurality of updated flow setpoint commands, each of which corresponds to one of the plurality of valves based on the the predicted adjustment. The processing device then sends each of the plurality of updated setpoint commands to the corresponding one of the plurality of valves.
