随着人们对飞机安全性、性能和经济性的日益重视，以及减少飞机对环境影响的需求，飞机推进系统的设计者面临着许多新的挑战。位于俄亥俄州克利夫兰的美国宇航局格伦研究中心（GRC）的控制和动力学技术分支正在领导和参与各种项目，与GRC内部和美国宇航局、美国航空航天工业和学术界的其他组织合作，开发先进的控制和健康管理技术，通过智能发动机的概念帮助应对这些挑战。智能发动机的关键使能技术是通过主动控制提高部件的效率，与智能发动机控制集成的高级诊断和故障诊断以提高部件寿命，以及在自适应容错架构中使用智能传感器和执行器的分布式控制。本文介绍了控制与动力学技术分支在主动部件控制和推进系统智能控制方面的活动，并介绍了在这些领域的一些最新分析和实验结果。
With the increased emphasis on aircraft safety, enhanced performance and affordability, and the need to reduce the environmental impact of aircraft, there are many new challenges being faced by the designers of aircraft propulsion systems. The Controls and Dynamics Technology Branch at NASA (National Aeronautics and Space Administration) Glenn Research Center (GRC) in Cleveland, Ohio, is leading and participating in various projects in partnership with other organizations within GRC and across NASA, the U.S. aerospace industry, and academia to develop advanced controls and health management technologies that will help meet these challenges through the concept of an Intelligent Engine. The key enabling technologies for an Intelligent Engine are the increased efficiencies of components through active control, advanced diagnostics and prognostics integrated with intelligent engine control to enhance component life, and distributed control with smart sensors and actuators in an adaptive fault tolerant architecture. This paper describes the current activities of the Controls and Dynamics Technology Branch in the areas of active component control and propulsion system intelligent control, and presents some recent analytical and experimental results in these areas.
