摘要

A grate-rotary kiln oxidized pellet sintering industrial process has the characteristics of mass transfer, heat transfer, and complex chemical reactions. In this study, an advanced control strategy framework of the rotary kiln sintering process based on an operation pattern optimization technology is established. By analyzing the performance index values of comprehensive working conditions, we have established a comprehensive working condition as the basis of whether to change the set-point values or not. Then, comprehensive judgment results are synthesized to obtain the related adjustment coefficients in order to modify the set-point values of the velocity of the rotary kiln and the coal injection quantity. A subtractive clustering method is used for realizing operation pattern matching. Finally, the simulation results show the effectiveness of the proposed coordinated optimization control strategy.
