PURPOSE:To obtain good controllability to a load change in a denitration ammonia control system. CONSTITUTION:The amount of NOx at a denitration ammonia outlet is detected by a detector 1 and, on the basis of the deviation value of the detection signal of the detector and an objective value 2, a learning potential function is formed by a multiplier 4 and an ammonia set value correcting operation signal maximizing the learning potential function is outputted from a differentiator 5 and the learning potential to a load change is operated by a learning potential comparing circuit 7 and a neuro-circuit containing function correcting a control gain in the direction enhancing the learing potential is constituted and the denitration ammonia set value 11 set by the function of the flow rate of fuel is corrected by the signal of the neuro-circuit. |
