摘　　要：半实物仿真是一种将部分硬件实物接入到仿真回路中的实时性仿真,该方法能够更加真实地反映系统的实际情况,具有更高的置信度。针对飞机电源系统中常用的三级无刷交流发电机,利用RT-LAB半实物仿真平台,并引入部分功率级元器件,搭建发电机的功率级仿真系统。该方法将RT-LAB与可控电源结合,通过RT-LAB实时运行发电机模型,输出的电压信号控制可控电源,模拟真实发电机的功率级电压,并采集可控电源的输出电压,从而实现三级无刷交流发电机闭环运行的功率级半实物仿真。Hardware-in-the-loop simulation is a real-time simulation which can reflect the actual situation of the system more realistically and increase confidence compared with digital simulation. A power simulation was built with some power level components based on RT-LAB using the three level brushless alternator as simulation object. This simulation model combine RT-LAB and controllable power source. The controllable power source was controlled by the output of RT-LAB generator model, and used the output as a feedback to the system. Thus the model completed a power level closed-loop feedback simulation.
