High Performance, Reliable and Efficient Fluid Power: Challenges in Controls, Diagnosis and Layouts

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才能操作的几个应用实例。然而，流体动力技术的发展速度还不够快，无法满足当今应用对高可靠性、高性能和高能效的要求。例如，飞机工业高度重视安全和性能，同时试图限制硬件冗余和减轻重量。与水下勘探一样，遥控液压机械手由于用户界面不佳而没有充分发挥其潜力。移动式液压设备，如挖掘机，由于控制阀的节流损失而能源效率低下。需要功能更强大、能效更高、可靠性更高的流体动力系统。

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.
