现代飞行控制系统研制过程中,飞行仿真试验是必不可少的重要步骤。三轴仿真转台则是半实物飞行仿真试验系统中最关键的设备,它用来真实复现飞行器在空中飞行时的角运动。目前，现有的三轴仿真转台不满足新型无人机仿真的特殊要求。本文介绍了一种适用于无人机仿真实验的三轴仿真转台控制系统的基本组成、总体设计及关键技术研究。关键词：ISA 总线 三轴转台 计算机控制 控制系统Abstract: In the design of modern flight control system, simulation examination is necessary. The three-axis simulation platform is the most important equipment in the examination, with which we display the movement of the aerocraft in the sky. Now the existing simulation platform couldn’t fulfill the especial requirement of the new UAV. So we design a set of new simulation platform for the new UAV. The basic form and work principium are introduced in this paper.KeyWords: ISA Bus; simulation; computer control; control system
