基于时序建模的仿真系统精度检测方法

Precision Detection Method of System Simulation Based on Time Series Modeling

系统仿真实验可以用来测试武器系统的性能,为了使得仿真测试正确可靠,需要对仿真的精度进行检测,时间序列建模分析是可行的方法。针对飞行模拟器仿真系统进行仿真系统的精度检测,首先对飞行模拟器输入与实际飞行系统相同的控制参数,比较两系统的输出飞行参数值,得到误差序列,然后对误差序列进行时间序列建模,来检测仿真系统的精度并进行稳定性检验。实验表明该方法能够有效判断仿真系统是否符合精度要求。

System simulation experiment can be used to test the performance of weapon. In order to guarantee simulation test reliable and correct, the simulation precision is need to test at first. Time series modeling analysis is feasible. Input same control parameter values to simulation system and practical system, their output parameter values and obtain the difference value series are compared. Then the difference value series will be modeled by time series modeling to detect stability and precision of the simulation system. The experiment indicated that the approach can iudze whether the simulation svstem measure up to precision demand or not effectivelv.
