Abstract - Kosanovich The manufacturing cost of chemicals can be decreased by improving the operating performance of chemical reactors. One way to accomplish this is through timely control of the operating variables. For batch systems, this is important to maintaining the quality of the final product. This research is to develop new robust, feedback control formulations for electrochemical batch processes that satisfy multiple performance objectives in the face of model uncertainties and disturbances. The formulation is general and can be applied to other batch systems as well. Specifically, this project consists of three studies on new fundamental approaches to the modelling and control of batch systems: (1) development of a time-varying state space model of the non-stationery batch process for use in a model predictive control strategy; (2) system identification using multi-resolution (wavelet) analysis; and (3) formulation of a controller strategy for a multi-resolution representation of the process. The research will include and experimental demonstration of the concepts on an electrochemical batch system. Effort will also be devoted to the development of effective computational procedures. The planned career advancement activities include six months of rigorous study in the methodologies, two summer months in a cooperative industrial program, and four months devoted to educational material preparation and experimental demonstration on a laboratory scale electrochemical batch process. The methodologies that are relevant to the goals of this study are (1) multi-resolution theory, (2) model predictive and optimal control theory; and (3) theory of electrochemical systems. The experimental portimn of the activities include a cooperative program that provides hands-on experience in the operations of systems at an industrial site and collaboration with department colleagues on electrochemical systems. Other activities include active participation in workshops and seminars, both do mestic and international, assistance of a post-doctoral research fellow, and development of a graduate control course that combines theory with experiments on batch systems.

摘要-科萨诺维奇 通过改善化学反应器的操作性能可以降低化学品的制造成本。 实现这一点的一种方法是通过及时控制操作变量。 对于批处理系统，这对于保持最终产品的质量非常重要。 本研究旨在开发新的鲁棒反馈控制配方，满足多个性能目标，面对模型的不确定性和干扰的电化学间歇过程。 该配方具有通用性，也可应用于其他间歇系统。 具体地说，该项目包括三项关于间歇系统建模和控制的新的基本方法的研究：（1）开发用于模型预测控制策略的非平稳间歇过程的时变状态空间模型;（2）使用多分辨率（小波）分析的系统辨识;以及（3）用于过程的多分辨率表示的控制器策略的制定。 该研究将包括电化学批处理系统的概念和实验演示。 还将致力于开发有效的计算程序。 计划中的职业发展活动包括六个月的严格学习方法，两个夏季的合作工业计划，以及四个月的教育材料准备和实验室规模的电化学批量过程的实验演示。 与本研究目标相关的方法是（1）多分辨率理论，（2）模型预测和最优控制理论;（3）电化学系统理论。 活动的实验部分包括一个合作计划，提供在工业现场系统操作的实践经验，并与电化学系统部门同事合作。 其他活动包括积极参加国内和国际的讲习班和研讨会，一名博士后研究员的协助，以及开发一门将理论与分批系统实验相结合的研究生控制课程。
