摘要

提出了一种动态实时优化(D-RTO)方法，并将其应用于聚合物接枝反应的间歇反应器中。目标是确定在线反应器温度分布，以最大限度地减少批处理时间，同时满足总体转化率和接枝效率的终端限制。该方法结合了约束动态优化方法和闭环控制中的移动视界状态估计器。结果表明，该方法在状态估计、约束实现和计算量等方面具有良好的性能。

Closed-loop dynamic optimization of a polymer grafting batch reactor

A dynamic real-time optimization (D-RTO) methodology has been developed and applied to a batch reactor where polymer grafting reactions take place. The objective is to determine the on-line reactor temperature profile that minimizes the batch time while meeting terminal constraints on the overall conversion rate and grafting efficiency. The methodology combines a constrained dynamic optimization method and a moving horizon state estimator within a closed-loop control. The results show very good performances in terms of state estimation, constraints fulfillment and computation load.
