项目摘要

Problem Statement: Aircraft flight control actuators, underwater hydraulic manipulators and off-highway machines are a few application examples that need hydraulic fluid power to operate. However, fluid power technology is not advancing fast enough to meet the high level of reliability, performance and energy efficiency required in today's applications. For example, aircraft industry places a high priority on safety and performance, while attempting to limit hardware redundancy and reduce weight. Teleoperated hydraulic manipulators, as in underwater exploration, are not used to their full potential due to poor user interfaces. Mobile hydraulic equipment such as excavators, are energy inefficient due to throttling losses in control valves. There is a need for more functional, energy efficient and reliable fluid power systems. Research Program: My research program aims at creating new tools that allow fluid power to not only perform the best in current practices, but also offer viable solutions for future applications. I propose to: (i) develop monitoring and control schemes aimed at locating and alleviating the effects of faults that degrade the performance of hydraulic systems, (ii) develop advanced techniques that allow operator-controlled hydraulic manipulators to interact effectively with dynamic environments, and (iii), design new hydraulic layouts and power management schemes for efficient utilization of energy supply in mobile hydraulics.Significance: The research on fault diagnosis and fault tolerant control design, will have an impact on enhanced control and fault monitoring of fluid power actuation used in a host of industrial sectors including aviation and automotive. The research on teleoperated control of hydraulic manipulators will have an impact on high performance manipulators suitable in field robotics. The research on energy efficient fluid power will contribute to the design of new off-highway machinery with smaller engines and reduced emissions.
问题陈述:飞机飞行控制执行器、水下液压机械手和非公路机械是需要液压流体动力来操作的几个应用示例。然而,流体动力技术的发展速度还不够快,无法满足当今应用所需的高水平可靠性、性能和能效。例如,飞机工业高度重视安全性和性能,同时试图限制硬件冗余并减轻重量。遥控液压机械手,在水下勘探,没有使用到他们的全部潜力,由于穷人的用户界面。诸如挖掘机的移动的液压设备由于控制阀中的节流损失而能量效率低。需要功能更强、能效更高且更可靠的流体动力系统。研究项目:我的研究计划旨在创造新的工具,使流体动力不仅在当前的实践中表现最好,而且还为未来的应用提供可行的解决方案。我提议:(i)开发监测和控制方案,旨在定位和减轻降低液压系统性能的故障的影响,(ii)开发先进技术,使操作员控制的液压机械手能够有效地与动态环境相互作用,(iii)设计新的液压布局和功率管理方案,以有效利用移动的液压系统中的能源供应。故障诊断和容错控制设计的研究,将产生影响,以增强控制和故障监测的流体动力驱动器中使用的主机工业部门,包括航空和汽车。液压机械手遥操作控制的研究将对开发适用于野外作业的高性能机械手产生重要影响。对节能流体动力的研究将有助于设计具有更小发动机和减少排放的新型非公路机械。
