Fluid power technology enjoys widespread use in a variety of applications: legged hydraulically powered walking machines, hydraulic robots, precision machine tools, flight control actuators, active suspension, motion simulators, excavator machines, and pneumatic prostheses. Traditional performance of fluid power actuators, however, no longer meets the current demands. Hydraulic manipulators are now required to perform cooperative tasks including handling a common object. Also, as an integral part of safety-critical systems such as aircraft, hydraulic actuators must maintain excellent performance even in the presence of faults. Pneumatic actuators are also in demand for new applications such as machine-mediated rehabilitation. Thus, it is essential to gain an in-dept understanding of the dynamics, and to develop advanced tools and supporting theories for robust control design and intelligent condition monitoring, of fluid power systems.

流体动力技术广泛应用于各种应用：有腿液压行走机、液压机器人、精密机床、飞行控制执行器、主动悬架、运动模拟器、挖掘机和气动假肢。传统的流体动力执行器的性能已经不能满足当前的要求。液压机械手现在需要执行协作任务，包括处理一个共同的物体。此外，作为飞机等安全关键系统的组成部分，液压执行器即使存在故障也必须保持优异的性能。气动执行器也需要新的应用，如机器介导的康复。因此，有必要深入了解流体动力系统的动力学，并开发先进的工具和支持理论，以实现流体动力系统的鲁棒控制设计和智能状态监测。
