Systematic Error Analysis Based on Hardware-in-the-loop Simulation Environment

针对某型反坦克导弹半实物仿真环境中构成环节复杂多样,出现误差呈现不同类型的问题,提出了一种基于该环境下的系统误差分析方法。通过分析仿真计算机、飞行运动模拟器、目标模拟器与仿真专用接口的构成特征与误差特性,得出仿真计算机的延时误差,飞行运动模拟器的机械安装误差,目标模拟器的延时误差与仿真专用接口的传输误差。通过对比各环节局部误差得出误差对仿真结果的影响。提出系统误差补偿方法,对该半实物仿真系统进行修正,通过仿真试验数据得出补偿修正有效。
