Mechatronic Design and Control of Media Handling Mechanisms for Printing Engines

这个GOALI研究项目的目标是研究在下一代复印机和打印机的媒体处理系统设计中使用先进传感器、驱动和决策方法的基本原理。复印机和打印机的许多问题都是由于介质处理系统的故障造成的。这些问题包括卡纸、由于即将卡纸而导致的机器关闭（软关闭）、涂抹、原始文档损坏以及编译不良。目前的介质处理系统是基于开环控制系统，并依赖于系统的机械设计的鲁棒性。传感器的使用仅限于检测故障，仅用于触发机器停机。这个工业界（施乐）和大学（伯克利大学）的联合研究项目解决了打印机和复印机中有关介质处理的问题。本研究在机电一体化、离散事件与混合动态系统、辨识与自适应控制、智能与可重构控制系统、故障检测与故障恢复、机械综合设计与控制等方面利用并取得进展。这项研究的结果将用于未来的复印机和打印机。消除介质处理系统中的堵塞将通过减少生产中的时间损失来提高生产率。目前每年因时间损失造成的产量损失价值为0美元。70亿年。处理高度非常宽的纸张的能力有助于降低造纸成本，并鼓励使用更经济的再生纸。最后，这项研究对于美国工业在极端竞争的复印机和打印机市场中保持技术领先地位至关重要。

The objective of this GOALI research project is to study fundamental principles for using advanced sensor, actuation and decision making methodologies in the design of media handling system for the next generation of copiers and printers. Many problems in copiers and printers are due to malfunctions in the media handling system. These include paper jams, machine shut downs due to impending paper jams (soft shutdown), smearing, damage to original documents, and poor compilation. Current media handling systems are based upon open-loop control systems and rely on the robustness of the system's mechanical design. The use of sensors is limited to the detection of failures and are only used to trigger a machine shutdown. This joint research project between the industry (Xerox) and the university (U C Berkeley) addresses the issues concerned with media handling in printers and copiers. The research utilizes and makes advances in: mechatronics, discrete event and hybrid dynamic systems, identification and adaptive control, intelligent and reconfigurable control systems, fault detection and failure recovery, and integrated mechanical design and control. The result from this research will be deployed in future copiers and printers. The elimination of jams in media handling system will improve productivity by reducing time lost in production. The current yearly lost production due to time lost is valued at $ 0. 7 Billion. The ability to handle paper of very wide lattitude serves to reduce cost of paper manufacturing and encourages the use of the more economical recycled paper. Finally, this research is of critical importance for American industries to maintain a position of technical leadership in the extreme competitive photocopier and printer markets.
