某型无人直升机飞行控制系统半实物仿真

摘要

Aiming at the actual demand of the performance ground test ofunmanned helicopter flight control system, research and design simulation platform for flight control performance test. Taking certain type "Single rotor coaxial fan" unmanned helicopter as example, gives the real-time working process of semi-physical simulation platform, establish math model according to dynamic knowledge, discuss design scheme, verify the platform function by hovering status simulation. The result show that the platform can similarly simulate the operating environment, verify the logic function and quality of the flight control system.%针对无人直升机飞控系统性能地面测试的实际需求,研究设计测试飞控系统性能优劣的仿真平台.以某型"单旋翼风扇共轴"式无人直升机为对象,给出半实物仿真平台实时工作流程,依据动力学知识进行数学建模,论述了设计方案等内容,通过悬停状态仿真对平台功能进行验证.结果表明:该平台可近似模拟飞控系统的运行环境,有效验证飞控系统的逻辑功能与品质.
