Wormlike micelles (WLMs), which are the self-assemblies of amphiphilic surfactants, have gained attention in various applications due to their unique ‘living’ nature (i.e., union-scission). However, the industrial production of the WLMs has rarely been discussed. Moreover, given that the system hardly reaches the desired viscosity without appropriate control actions within a reasonable operation time, a model-based controller has been implemented to the production of WLMs where CTAB/NaCl in a semi-batch reactor is used as a case study. For this, a high-fidelity model was developed by integrating thermodynamic, kinetic, and rheology models and validated with experimental results. Subsequently, to alleviate the computational burden of such a high-fidelity model, the model reduction was carried out by the multivariable output error state space algorithm. The developed reduced-order model (ROM) was able to reproduce the essential features of the high-fidelity model and utilized in the formulated model predictive control (MPC) system. Herein, the manipulated variables (i.e., surfactant volume fraction, salt concentration, and temperature) are adjusted to give the desired WLM length of 3700 nm (i.e., a zero-shear viscosity of 100 Pa-s). Finally, the developed MPC scheme resulted in optimal input sequences to successfully reach the setpoint within practical constraints.

蠕虫状胶束 (WLM) 是两亲性表面活性剂的自组装物，由于其独特的“活”性质（即断联），已在各种应用中受到关注。然而，WLM 的工业生产很少被讨论。此外，鉴于在合理的操作时间内没有适当的控制措施，系统很难达到所需的粘度，基于模型的控制器已被应用于生产 WLM，其中以半间歇式反应器中的 CTAB/NaCl 作为案例研究. 为此，通过整合热力学、动力学和流变学模型开发了一个高保真模型，并通过实验结果进行了验证。随后，为了减轻这种高保真模型的计算负担，通过多变量输出误差状态空间算法进行模型约简。开发的降阶模型 (ROM) 能够重现高保真模型的基本特征，并在公式化模型预测控制 (MPC) 系统中使用。在此，调节操纵变量（即，表面活性剂体积分数、盐浓度和温度）以提供所需的 3700 nm 的 WLM 长度（即 100 Pa-s 的零剪切粘度）。最后，开发的 MPC 方案产生了最佳输入序列，以在实际约束内成功达到设定点。表面活性剂的体积分数、盐浓度和温度）进行调整，以获得所需的 3700 nm 的 WLM 长度（即 100 Pa-s 的零剪切粘度）。最后，开发的 MPC 方案产生了最佳输入序列，以在实际约束内成功达到设定点。表面活性剂的体积分数、盐浓度和温度）进行调整，以获得所需的 3700 nm 的 WLM 长度（即 100 Pa-s 的零剪切粘度）。最后，开发的 MPC 方案产生了最佳输入序列，以在实际约束内成功达到设定点。
