机载武器捷联惯导系统传递对准仿真环境研究

为了更加真实准确地研究机载武器的传递对准过程,设计了一个能够分别模拟主子惯导IMU输出,并包括杆臂效应补偿、机翼振动模型和IMU误差模型在内的用于传递对准研究的仿真环境。建立了滚转角辅助倾斜转弯下的姿态角速度模型,提出并建立了包括安装误差角在内的惯性器件误差模型。通过仿真表明,该仿真环境比较真实地反应了实际的飞行轨迹,既可以作为研究传递对准算法的工具,也为更进一步研究传递对准过程提供了平台基础。

Research on Simulation Environment of Transfer Alignment for Airborne Weapon SINS

In order to study transfer alignment of airborne weapon more accurately,a simulation environment used in study on transfer alignment is presented,which contains IMU output data of master INS and slave INS,lever-arm compensation,wing flexure models and IMU sensor error models.Attitude angle rate models of coordinated turn and mounting error models of IMU sensors are developed.The results show that the simulation environment is used in study on transfer alignment successfully,and lays the foundation of study ...
