GOALI: Method of Tuning and Automatic Regulation for Injection Molding

9700288 Danai这项目标研究的目标是开发一种高效和可靠的方法来调整和调节注塑成型过程，以便能够容易地实现所需的注塑零件质量，并一致地确保用于商业生产。该方法的一个重要特点是能够选择在满足零件质量约束的同时将生产成本降至最低的机器投入。研究将在理论和应用两个层面进行，并与行业合作伙伴密切互动。在理论层面：(1)将修改I-0模型的形式，以便纳入零件性能的定性测量；(2)将过程动力学整合到I-0模型中，以增强在存在过程瞬变和外部变化时的稳健性；以及(3)将在虚拟搜索方法(VSM)中采用优化策略，以折衷产品质量以降低产品成本。在应用层面，GE塑料公司将与其他行业联络人进行广泛的行业合作计划，以确定生产的严格要求。在这一阶段的研究中获得的应用要求的解决方案预计将为VSM的广泛传播做好准备。该项目将提供有价值的杠杆作用，为注塑行业提供区域过程控制器方面的基础知识

9700288 Danai The objective of this GOALI research is to develop an efficient and robust method of tuning and regulation for injection molding processes, so that the desired quality of injection molded parts can be readily achieved and consistently ensured for commercial production. An important feature of this method will be its ability to select the machine inputs that will minimize production cost while satisfying the part quality constraints. The research will be conducted at both theoretical and applied levels with close interaction with industry partner. At the theoretical level: (1) the form of the I-0 model will be revised to allow for incorporation of qualitative measures of part properties; (2) process dynamics will be integrated in the I-0 model in order to enhance robustness in presence of process transients and external variations; and (3) an optimization strategy will be adopted in the virtual search method (VSM) to trade off product quality for reduced product costs. At the applied level, an extensive industrial collaboration program will be conducted at GE Plastics with other industry liaisons to identify the stringent requirements of production. The solutions obtained to the application requirements in this phase of research are expected to prepare VSM for wide area dissemination. This project will provide valuable leveraging to contribute fundamental knowledge in the area process controller for the injection molding industry
