9503021 Alexander This research will be undertaken as part of the CRISP (Combined Research Industry Scholarship Project) under the 1994-95 GOALI (Grants Opportunities for Academic Liaison with Industry) initiatives. The aim of the GOALI initiatives was to provide some mechanism to encourage and promote industry-university partnerships to work on research problems of interests to industry. It is believed that such partnerships can grow and lead to other meaningful joint industry-university research projects that can be of benefit to both industry and academia. The industrial partner for this research is Liqui-Dri Foods, a Division of Quaker Corporation. The objective of the research is to reduce process variability with an emphasis on improving the control systems of fill process lines at Liqui-Dri/Quaker. The control systems were designed to keep four filling lines at Liqui-Dri/Quaker on target. However, the workers tend to shut off these control systems because they feel the control systems are slow to react. This study is aimed at integrating monitoring systems with the automatic control systems in order to detect the changes in the underlying process models used by the control systems to predict system state. In the research, a diagnostic module will be used to determine the form of the disturbances and probable causes of system instability. The design and use of fuzzy controllers for controlling the process will also be investigated. Due to its applied nature, the participants on this project stand to draw some significant benefits from it. For the industrial partner, control of process variability will translate to enhanced product quality and reduced losses due to potential overfill. The reliability of the system will be enhanced. From the academic points of view, the researchers will gain some practical experiences on a real industrial problem. However, on a more general perspective, outcome of this research can be applied to a host of industrial problems where close m itering and monitoring are critical to line reliability and functionality.

这项研究将作为1994-95年GOALI（与工业界学术联络的资助机会）倡议下的CRISP（联合研究产业奖学金项目）的一部分进行。GOALI计划的目的是提供一些机制，鼓励和促进产学研伙伴关系，共同研究工业界感兴趣的研究问题。相信这样的伙伴关系可以发展，并导致其他有意义的产学研联合项目，可以使工业界和学术界都受益。这项研究的工业合作伙伴是Quaker公司旗下的liquid - dri Foods。研究的目的是减少过程的可变性，重点是改进liquid - dri /Quaker灌装生产线的控制系统。控制系统的设计是为了保持四条灌装线在liquid - dri /Quaker的目标。然而，工人们往往会关闭这些控制系统，因为他们觉得控制系统反应缓慢。本研究旨在将监控系统与自动控制系统相结合，以检测控制系统用于预测系统状态的底层过程模型的变化。在研究中，诊断模块将用于确定干扰的形式和系统不稳定的可能原因。本文还将研究模糊控制器的设计和应用。由于它的应用性质，这个项目的参与者将从中获得一些显著的好处。对于工业合作伙伴来说，过程可变性的控制将转化为提高产品质量和减少由于潜在的过度填充造成的损失。系统的可靠性将得到提高。从学术角度来看，研究人员将在一个实际的工业问题上获得一些实践经验。然而，从更广泛的角度来看，本研究的结果可以应用于许多工业问题，其中近距离监测和监测对线路可靠性和功能至关重要。
