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-Kosanovich通过改善化学反应器的工作性能，可以降低化学品的制造成本。 实现此目的的一种方法是及时控制操作变量。 对于批处理系统，这对于保持最终产品的质量很重要。 这项研究是为了在模型的不确定性和干扰时为电化学批处理过程开发新的强大的反馈控制配方，以满足多个性能目标。 该公式是一般的，也可以应用于其他批处理系统。 具体而言，该项目包括三项有关批处理系统建模和控制的新基本方法的研究：（1）开发非机构批处理过程的随时间变化的状态空间模型用于模型预测性控制策略； （2）使用多分辨率（小波）分析的系统识别； （3）为过程的多分辨率表示制定控制器策略。 该研究将包括和实验证明电化学批次系统上的概念。 努力也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在方法论中进行六个月的严格研究，在合作工业计划中进行了两个夏季，以及四个月专门用于教育材料准备和实验室规模电化学批次过程的实验演示。 与本研究目标相关的方法是（1）多分辨率理论，（2）模型预测和最佳控制理论； （3）电化学系统理论。 该活动的实验性Portimn包括一个合作计划，该计划在工业网站的系统运营中提供动手经验，并与部门同事在电化学系统上合作。 其他活动包括积极参与研讨会和研讨会，包括世界和国际，博士后研究员的帮助，以及将理论与批处理系统实验相结合的研究生控制课程的发展。
