摘要:本文首先提出了一種試探式預測控制算法,可方便地對非線性被控過程實施預測控制。在此基礎上,針對SCR脫硝過程具有明顯非線性及控制作用受限的特點,提出了基于試探式預測控制技術的火電機組SCR脫硝優化控制系統,實際應用表明,新型的SCR脫硝優化控制系統不僅有效地減小了NOx的波動量,而且有效減少了氨氣使用量,確保了SCR脫硝系統的穩定、經濟運行。

Abstract: a new tentative predictive control (TPC) algorithm is proposed in the paper, which is easy to be implemented for non-linear controlled process. Furthermore, according to nonlinear features and limited control action of SCR denitration process, a new SCR denitration optimization control system with tentative predictive control technology is presented. Practical application shows that this new control system reduces both the fluctuation of NOx amount and the requirement of ammonia,and assures the stability and economy of the SCR denitration system.
