摘要：

Servo Motor Pumps（SMP）play a decisive role as central power and control elements for the performance limits in Electro-Hydrostatic Actuators （EHAs）. Internationally renowned hydraulic companies such as Moog and Parker have introduced SMPs for aerospace and high value Industrial applications. In recent years，Chinese research in the field of high-performance SMPs has made some progress，but is still far from mature. This article provides a comprehensive overview of SMPs in terms of aerospace applications and also considers other fields such as robotics，marine and industrial applications. Based on the analyzed applications and developments，the five key performance characteristics such as high power-to-weight ratio，high dynamic range，long service life，low noise and intelligence are summarized，and the difficulties in theory and key technologies are discussed to make suggestions for high-performance EHAs and their key components. © 2024 Chinese Society of Astronautics.
