A Multiple Model Control Method of Coal-Fired Power Plant SCR-DeNOx System
Nowadays, energy consumption problem and air contamination affecting the quality of our lives horribly is becoming more and more serious. Industrial emission issues have attracted much attention specially. As a crucial index, the denitration efficiency of Selective Catalytic Reduction (SCR) system, which is the primary way to control emission of NOx in coal-fired power plant, is normally required above 80%. In this paper, Fractional Order Proportional Integral Differential based on Internal Model Control (IMC-FOPID) controller is introduced to control the emission of NOx by implementing multiple model strategy. Compared with traditional PID controllers, the proposed control method in this paper is more effective.
