The ratio control structure with two adaptive blend stations

Abstract

In this paper, a ratio control structure with two adaptive Blend stations is proposed. Except providing a high ratio performance for set-point changes and load disturbance that accurs in the first loop, the proposed structure achieves to keep the value of YZ/Yl close to the desired ratio a when load disturbance happens in the second loop. In order to demonstrate the effectiveness of the proposed method, the Blend ratio control structure also simulate with the same two processes and the results are compared with each other. Simulations are all realized by Labview .
