Title:
PROPORTIONAL MIXING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/125671
Kind Code:
A1
Abstract:
Provided is a highly precise system for controlling proportional mixing, wherein the proportional mixing system is capable of maintaining the mixture ratio of flow rates of a primary liquid and a secondary liquid at a predetermined target mixture ratio. This highly precise proportional mixing system holds the mixture ratio of flow rates of a primary liquid and a secondary liquid constant while recognizing an error integrated retroactively using the integrated flow rate of the primary liquid and the secondary liquid. This highly precise proportional mixing system also estimates future integrated error from past error trends to control the instantaneous flow rate of the primary liquid and/or secondary liquid.
