项目摘要
PROBLEM STATEMENT: Fluid power is essential for the operation of critical systems in many fields, like aircraft flight control actuators, teleoperated manipulators for underwater exploration or nuclear services, offshore wind turbines and off-highway vehicles. In its present form, however, fluid power technology is not advancing fast enough to meet the growing reliability, performance and efficiency demands of these applications. For example, safety-critical aircraft demand that hydraulic flight actuators be equipped with on-line fault monitoring tools and be able to maintain good performance in the presence of faults. Presently, these requirements are fulfilled through hardware redundancy, pilot intervention and frequent maintenance. Hydraulic manipulators are now required to cooperatively work together and with operators to perform synchronized tasks that involve interacting with unstructured environments. There is an urgent need for new energy efficient hydraulic systems capable of energy regeneration while maintaining the high performance demanded by machine operators of mobile hydraulic equipment.
RESEARCH PROGRAM: My research program strives to improve the dynamics and control of fluid power systems and develop solutions for enhanced reliability, high performance, advanced operator interfaces, and efficient use of energy in both current and future applications. Over the next 5-year cycle, I propose to: (i) develop easy to implement fault tolerant control and fault diagnosis schemes capable of locating and alleviating the effects of various faults that degrade the performance of hydraulic systems, (ii) synthesize advanced control techniques that allow operator-controlled hydraulic/pneumatic manipulators to effectively interact, individually or cooperatively, with unstructured environments and (iii), design new hydraulic layouts and power management schemes for efficient energy use in mobile machines.
SIGNIFICANCE: The proposed research will lead to enhanced condition monitoring of fluid power systems and lower overall risk of downtime in many industrial sectors including aviation, automotive and field machinery. My research on controller design for hydraulic manipulators will enable a new generation of teleoperated multiple-arm hydraulic manipulators that are useful for remote tasks as in underwater/rescue operations. My research on energy efficient mobile hydraulics will allow my lab to play an active role at the international level, and develop modernized off-highway machinery with smaller engines and reduced emissions. During the course of this research many students will be trained in all aspects of fluid power system research using my unique, state-of-the-art laboratory. These trainees will become the next generation of fluid power experts who will contribute their distinctive expertise to Canadian industry in many practical ways.
问题陈述:流体动力对于许多领域的关键系统的操作至关重要,例如飞机飞行控制执行器,水下勘探或核服务的遥控操纵器,海上风力涡轮机和非公路车辆。然而,以其目前的形式,流体动力技术的发展速度还不够快,无法满足这些应用日益增长的可靠性、性能和效率需求。例如,安全关键型飞机要求液压飞行致动器配备有在线故障监测工具,并且能够在存在故障的情况下保持良好的性能。目前,通过硬件冗余、飞行员干预和频繁维护来满足这些要求。液压机械手现在需要协同工作,并与操作员执行同步任务,涉及与非结构化环境的互动。迫切需要能够再生能量同时保持移动的液压设备的机器操作者所要求的高性能的新的节能液压系统。
研究报告:我的研究项目致力于改善流体动力系统的动力学和控制,并开发解决方案,以提高可靠性,高性能,先进的操作界面,并在当前和未来的应用中有效利用能源。在下一个五年周期,我建议:(i)开发易于实施的容错控制和故障诊断方案,能够定位和减轻降低液压系统性能的各种故障的影响,(ii)综合先进的控制技术,使操作员控制的液压/气动机械手能够单独或合作地与非结构化环境有效地相互作用,以及(iii),为移动的机器设计新的液压布局和电源管理方案,以实现高效的能源利用。
重要性:拟议的研究将增强流体动力系统的状态监测,并降低包括航空、汽车和现场机械在内的许多工业部门的总体停机风险。我对液压机械手控制器设计的研究将使新一代的遥控多臂液压机械手,是有用的远程任务,如在水下/救援行动。我在节能移动的液压方面的研究将使我的实验室在国际上发挥积极作用,并开发具有更小发动机和减少排放的现代化非公路机械。在这项研究的过程中,许多学生将使用我独特的,最先进的实验室在流体动力系统研究的各个方面进行培训。这些学员将成为下一代的流体动力专家,他们将以许多实际的方式为加拿大工业贡献自己独特的专业知识。
