Real time is necessary for the hardware-in-the-loop simulation. In order to evaluate the real-time performance of the hardware-in-the-loop simulation of a small flight control system, several indices are adopted. After investigating the different parts of the simulation platform, experimental data of the real-time indices is given. The data may be useful for evaluating the credibility of the hardware-in-the-loop simulation results.%实时仿真是半实物仿真的基本要求.为了评价某小型无人机飞控系统半实物仿真平台的实时性,提出了实时性的评价指标,研究了仿真平台各组成部分对实时性的影响,并给出了实验数据.该数据对评价无人机飞控系统半实物仿真结果的可信度有一定参考价值.
