中文摘要：

飞机电力作动器是未来飞机电源系统的重要负载，对电源系统的质量和稳定性问题有很大影响，通常要在电力系统全集成之前进行半实物仿真。本文首先介绍该种飞机电力作动器半实物仿真理论实现方法，然后县体通过电力作动器动态功率特性、恒功率特性、电源输入阻抗特性及电磁兼容性几个方面对该疗法的可行性进行了一定程度的论证，最后介绍了该种飞机电力作动器半实物仿真具体的硬件实现方法。

英文摘要：

The Electric actuator is an important load of future airplane and has an influence on the quality and stability of power system. In order to avoid the problems of aero power system during integration period, hardware-in-the-loop simulation is necessary in the course of manufacture. This paper first introduces a hardware-in-the-loop simulation method of Electro-Mechanical Actuator, then demonstrates the feasibility of this simulation from several aspects such as dynamic power characteristic, constant power characteristic, input impedance characteristic and EMC （Electro Magnetic Compatibility） characteristic of the power system. In the end, a realization of hardware system will be introduced.
