平台式/捷联式惯导传递对准仿真平台的实现

讨论了一种在Matlab中建立快速传递对准数学模型,并在VC 下运用MATCOM实现传递对准仿真平台的方法。传递对准采用“速度/角速度匹配”方案,仿真结果证明,该方案的对准精度优于国内传递对准的仿真精度要求,具有实际参考价值。传递对准仿真平台能够设置主、子惯导的各项仿真参数,适应不同精度的惯导系统的仿真要求,并能够规划多种航迹,用于传递对准方案的精度评估,为实际飞行中的动基座快速对准提供参考,并大大降低了传递对准仿真的工作量。

Realization of transfer alignment emulator for platform/strapdown inertial navigation system

A method is proposed to establish rapid transfer alignment model in Matlab,and carry out a transfer alignment emulator using MATCOM under VC .The transfer alignment adopts the "velocity/ angular velocity" project.Simulation results prove that,the precision of the project exceeds the civil emulation precision requirement of transfer alignment,and the project has practical referenced value.The transfer alignment emulator can set up various parameters of master and slave inertial navigation systems to fit the emulation requirement of inertial navigation systems,which are different in precision.The emulator can also mark out various flight path models and evaluate the precision of alignment to supply reference for fast transfer alignment on moving base during practical flight,and to lighten the workload of transfer alignment emulation.
