摘要
功率电传作动系统是"多电飞机"的重要组成部分,而液压能源集成技术是其核心技术,在飞机技术变革中扮演着至关重要的角色。本文首先分析了发展功率电传作动系统的必要性,并以电液作动器(EHA)为例对国内外研究现状进行了介绍;其次,给出了液压能源集成技术的历史沿革及研究现状,并对永磁电机在该领域的应用优势进行了阐述;最后,对系统建模、控制率等液压能源集成系统的关键技术进行了阐述,在此基础之上对液压能源集成技术的发展趋势进行了展望。
Powerbywire draulic energy integration technological change （PBW） actuator system is a important component of more electric aircraft. Hytechnology is core technology of PBW actuator system, and plays a critial role in of aircraft. In this paper, the necessity to develop PBW actuator system was analyzed firstly, and took electrical hydraulic actuator （EHA） as an example to introduced the research status. Then the historical evolution and research status of hydraulic energy integration system were given, and the application advantages of permanent magnet machine in this field were exposited. Finally, the key technologies of hydraulic energy integration system were summarized and its development trend was presented.
