Collaborative Research: Sensing and Control of Digital Color Xerographic Imaging Systems

普渡大学、明尼苏达大学和施乐公司之间的合作研究和教育关系正在形成，以从事为390亿按需印刷行业的传感和控制开发新的理论视角的高风险和高回报任务。工业-大学研究团队的职责是对数字彩色静电印刷的传感和控制问题有基本的了解，并开发实用的和理论上健全的控制系统，以扩展打印系统的操作范围，同时以可预测的方式产生一致的高质量打印。我们的方法将1)在控制分析和综合中使用现有的人类视觉感知模型，2)利用过程元素来最大化感知和驱动机会，3)使用协调原则来实现最终的性能目标，4)利用空间和时间系统表示之间的转换。通过这一努力开发的方法学和以控制为中心的系统方法将显著提高数字彩色干版印刷的图像质量。这项技术将有助于推动该行业进入一个新时代，并保持美国短期和办公打印行业的竞争优势。控制策略和设计方法将适用于其他打印和成像系统，如喷墨打印机、图像扫描仪和显微镜。

A collaborative research and education relationship among Purdue University, University of Minnesota, and Xerox Corporation is being formed to engage in the high risk and high payoff task of developing new theoretical perspectives for sensing and control for the 39 billion on-demand printing industry. The charge of the industry-university research team is to develop fundamental understanding of the sensing and control issues for digital color xerography and to develop practical and theoretically sound control systems that expand the operation envelop of printing systems while producing consistent, high quality prints in a predictable manner. Our approach will 1) use existing models of human visual perception in control analysis and synthesis, 2) exploit process elements to maximize sensing and actuation opportunities, 3) use the principle of coordination to achieve the final performance objectives, and 4) exploit the transformation between spatial and temporal system representations. The methodology and control-centric system approach developed by this endeavor will significantly improve the image quality of digital color xerography. This technology will help propel the industry to a new era and maintain the competitive edge of the U.S. short-run and office printing industry. The control strategies and design methodologies will be applicable to other printing and imaging systems, such as inkjet, image scanners and microscopy.
