Abstract
An apparatus and method for combining multiple materials. The multiple materials may include both a major material and one or more minor materials. The major and minor materials are added at transient or steady state flow rates, depending upon a command from a control signal. The actual flow rates track the commanded flow rates, but deviate by an error. The claimed arrangement provides an instantaneous and time-based error believed to be unobtainable in the prior art.
