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. ********************

问题声明：流体功率对于许多领域的关键系统的运行至关重要，例如飞机飞行控制器，用于水下勘探或核服务的遥控器，海上风力涡轮机和非公路车辆。但是，以目前的形式，流体力技术的发展不足以满足这些应用程序增长的可靠性，性能和效率需求。例如，安全至关重要的飞机要求配备液压飞行执行器在线故障监控工具，并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，试点干预和频繁维护来满足这些要求。现在需要液压操纵器一起合作，并与操作员一起执行涉及与非结构化环境进行交互的同步任务。迫切需要新的能源再生的液压系统，同时维持移动液压设备的机器运营商所需的高性能。*** *** ***研究计划：我的研究计划致力于改善流体动力系统的动态和控制，并开发解决方案，以增强可靠性，高性能，高性能，高级运营商的交互和能源在当前和未来的应用程序中有效地使用。在下一个5年周期中，我建议：（i）开发易于实施可容忍的控制和故障诊断方案，能够定位和减轻各种故障的影响，从而降低液压系统的性能，（ii）合成的高级控制技术，以使操作员允许操作员和液压/机器人的互动，或有效地互动，或合成的环境，或者有效地进行了工具，或合成的效果，或者有效地互动，或合成。新的液压布局和电源管理方案，用于在移动机器中有效使用能源。 ******重要性：拟议的研究将导致流体动力系统的状况监测增强，并降低许多工业部门的总体停机风险，包括航空，汽车和现场机械。我对液压操纵器的控制器设计的研究将使新一代的远程手术多臂液压操纵器能够像水下/水下/救援行动一样有用。我对节能移动液压技术的研究将使我的实验室能够在国际层面发挥积极作用，并使用较小的发动机和减少排放的现代化高速公路机械。在这项研究过程中，许多学生将使用我独特的最先进的实验室在流体电力系统研究的各个方面进行培训。这些受训者将成为下一代流体能力专家，他们将以许多实际的方式为加拿大行业贡献其独特的专业知识。 ********************
