摘　　要：分析了干熄焦生产中与焦炭预存量有关的因素,建立了干熄炉内焦炭预存量的数控模型。利用迭代优化策略,使系统不断对公式进行计算、优化和迭代补偿,从而使模型失配、时变、干扰等引起的不确定性及时得到弥补,有效防止了红焦外溢和炽热红焦排出损坏设备等重大事故的发生。The relevant factors in CDQ production and coke pre-storage were analyzed, the math control model of coke pre-storage in CDQ chamber was established. By means of iterative and optimum policy, the system continuously calculated, optimized, iterated and compensated to the formula, so that the uncertainty caused by the model mismatch, time variation and interference can be timely compensated, the occurrence of major accidents such as the equipment damage caused by red hot coke overflow and discharge can be effectively avoided.
