对苯乙烯与α-甲基苯乙烯间歇共聚反应器进行了优化。反应器配备有用于热交换的夹套，从而用于温度控制。性能指标为间歇周期，决策变量为夹套进口温度。所涉及的约束条件包括工艺模型、聚合物质量、最终单体转化率、反应器的加热/冷却速率以及变量的上界和下界。优化方法是一种直接的方法与顺序的策略称为控制矢量参数化方法。在处理和满足约束条件方面非常谨慎地确定最佳配置文件。结果表明，相对于以前使用的完整的离散化方法有很大的改善。
This paper addresses the optimization of a batch copolymerization reactor of styrene and α-methylstyrene. The reactor is equipped with a jacket for heat exchange and, thus, for temperature control. The performance index is the batch period, and the decision variable is the jacket inlet temperature. The constraints involved include the process model, the polymer quality, the final monomer conversion rate, the heating/cooling rate of the reactor and upper and lower bounds of the variables. The optimization method is a direct method with a sequential strategy known as control vector parametrization method. The optimal profiles are determined with great care in terms of treatment and fulfilment of constraints. The results show a substantial improvement with respect to the complete discretization method previously used.
