SST: Control-oriented Optimal Multisensor Design and Microfabrication for Structural Vibration Suppression in Mechatronic Systems (GOALI)

[0428917]加州大学伯克利分校的robotp horowitz在这个项目中，以磁性硬盘驱动器为背景来研究传感器开发中的两个问题。首先，对于柔性结构的闭环和减振控制，需要多少个传感器，它们的最佳位置是什么？其次，如何将微尺度应变和振动传感器制造技术纳入传统的制造环境？将开发新的面向控制的技术，用于集成设计，制造和放置用于机电系统中振动抑制控制和监测的多个传感器，并将其与钢基板上的MEMS传感器制造技术集成在一起，以开发这样的技术。该项目的工业合作伙伴和记黄埔科技有限公司（HTI）将把制造的基板与成品传感器组装成磁性硬盘驱动器的原型悬架。这些仪器悬架将与项目研究团队已经制造的MEMS微致动器结合到双级伺服系统中，以评估其性能。该项目将为学生提供学习机电一体化设计方法的机会，该方法将控制系统理论设计和分析方法与CAD， FEM和机械设计优化方法紧密结合，同时开发新的MEMS加工技术，将传感器嵌入金属机械设备。这是由传感器倡议NSF 04-522支持的GOALI项目。

Abstract0428917Robotp HorowitzUniv Calif/BerkeleyIn this project magnetic hard disk drives are used as the context to examine two problems in sensor development. First, how many sensors are necessary and what are their optimal placements for closed-loop and vibration suppression control of a flexible structure? Second, how can micro-scaled strain and vibration sensor fabrication techniques be incorporated into traditional manufacturing environments? Novel control-oriented techniques for the integrated design, fabrication and placement of multiple sensors for vibration suppression control and monitoring in mechatronic systems will be developed and integrated with MEMS sensor fabrication techniques on steel substrates to develop such a technology. Hutchison Technologies Inc. (HTI), the industrial partner in this project, will assemble the fabricated substrates with the finished sensors into prototype-instrumented suspensions for magnetic hard disk drives. These instrumented suspensions will be incorporated into dual-stage servo systems with MEMS microactuators already fabricated by the project research team, for evaluation of their performance.The project will provide students with the opportunity to learn mechatronic design approaches that cohesively integrate control systems theoretic design and analysis methodologies with CAD, FEM and mechanical design optimization methodologies, while simultaneously developing new MEMS processing techniques for embedding sensors into metal-mechanic devices.This is GOALI project supported under Sensors Initiative NSF 04-522.
