9632801 Koditschek This proposal describes an approach to the control of xerographic printing that, if successful, promises to advance the state of the art in the industry, help lead Xerox Corporation into a $80B new market, and considerably enlarge the academic community's experience with application of robust, nonlinear, and intelligent controls techniques in competitive, fast moving consumer markets. The chief technical objective is a dramatic improvement in the process stability of dry powder color xerography. The long term goal is to demonstrate this level of stability in all relevant environmental zones (temperature, relative humidity), a variety of paper types and colors, and over a number of machines. A second contribution will be the development of a new controls oriented design support methodology. The approach to this problem will be driven by a "problem solving" focus (rather than a "theory driven focus") to creatively combine the strengths of the researchers at the Wilson Research Center with the academic researchers at the University of Michigan. Preliminary discussions suggest a hierarchical controller whose lower level specifies process parameters using robust (nonadaptive) nonlinear controller techniques with a higher level specification of the product parameters using model driven adaptive or possibly learning techniques. The control algorithms and architectures developed in this project will be assessed for product-worthiness with respect to the standard Xerox Field Readiness Determination Testing procedures. ***

该提案描述了一种控制静电印刷的方法，如果成功，将有望推动该行业的最新技术，帮助施乐公司进入800亿美元的新市场，并大大扩大学术界在竞争激烈、快速发展的消费者市场中应用强大、非线性和智能控制技术的经验。主要的技术目标是大幅度提高干粉彩色静电照相的工艺稳定性。长期目标是在所有相关的环境区域（温度，相对湿度），各种纸张类型和颜色以及许多机器上证明这种水平的稳定性。第二个贡献将是开发一种新的面向控制的设计支持方法。解决这个问题的方法将由“解决问题”的重点（而不是“理论驱动的重点”）来驱动，以创造性地结合威尔逊研究中心研究人员和密歇根大学学术研究人员的优势。初步讨论提出了一种分层控制器，其较低层次使用鲁棒（非自适应）非线性控制器技术指定过程参数，较高层次使用模型驱动的自适应或可能的学习技术指定产品参数。在这个项目中开发的控制算法和架构将根据标准的施乐现场准备确定测试程序来评估产品价值。* * *
