Abstract: Power-by-wire (PBW) actuator system is a important component of more electric aircraft. Hydraulic energy integration technology is core technology of PBW actuator system, and plays a critial role in the technological change 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.
