摘要
基于某型无人机飞行控制系统仿真实验的要求,设计了一种可用于半物理仿真的大气数据模拟器,详细阐述了模拟器的实现方案和具体功能。针对气压控制回路的延时特性,采用了复合控制方式,使系统带宽达到飞行仿真系统的要求。仿真结果表明:该大气数据模拟器具动态性能好,稳态精度高,能很好地用于无人机飞行控制系统的半实物仿真。
An air data simulator for a UAV flight simulation system was presented. The realization method and function of air data simulator were discussed in detail. According to the delay characteristic of air pressure loop, composite control method was adopted to make the bandwidth meet the requirement of flight simulation system. The air data simulator showed high dynamic performance and accuracy, which indicated that it eould be used in hardware-in-the-loop simulation for UAV flight control system.
