摘要： PURPOSE: A gas mixing control device and a method for controlling gas mixing ratio therein are provided to prevent the errors of a gas mixing ratios by possessively adjusting the target flow rate of the element gas. CONSTITUTION: A method for gas mixing ratio in a gas mixing control device is as follows. The control device transmits each target flow rate value predetermined by target mixing ratio to multiple flow rate controllers for controlling flow rate in multiple pipes(S330). The control device receives the actual flow rate values of each outlet of the pipes from the flow rate controllers(S340). The control device corrects the target flow rate value for the flow rate controllers for controlling the flow rates in rest pipes except for pipes in which the target flow rate value and the practical flow rate values are escaped from a predetermined error range. The control device receives the corrected target flow rate value to the flow rate controllers for controlling the flow rate of the rest pipes.
