聚合反应器是高分子化学工业的关键设备。此文主要研究工业规模苯乙烯悬浮聚合反应器质量优化控制问题。通过分析该间歇式反应器系统状态间内部联系,提出了两种控制方案。其一是采用自校正控制器严格控制釜温,以达到质量优化控制的目的,但对质量成分的控制是开环的。其二对产品质量是带有闭环性质的控制方案,它是针对投料失误、外部其他干扰的影响,而使第一方案无法保证反应器的质量优化控制而提出的。该方案的特点在于借助状态估计器,将反映产品质量的反应器状态反馈回输入端,利用文中介绍的优化调整算法,在线调
Polymerization reactor is the key equipment of polymer chemical industry. This article mainly studies the industrial scale styrene suspension polymerization optimization of quality control problems. By analyzing the internal relations between the system states of the batch reactor, two control schemes are proposed. One is the use of self-tuning controller strict control of the kettle temperature, in order to achieve the purpose of quality control optimization, but the quality control of the composition is open-loop. The other two pairs of product quality control programs with closed-loop nature, it is for feeding errors, the impact of other external interference, leaving the first program can not guarantee the quality of the reactor optimal control and made. The program is characterized by the use of state estimator, will reflect the quality of the reactor state feedback to the input, using the optimization algorithm described in the article, online tune
