Simulation precision detection method of flight system based on time series modeling

飞行系统仿真实验可以用来测试飞机的性能,为使仿真测试过程正确可靠,需要对仿真的精度进行检测。采用时间序列建模分析的检测方法。对仿真系统输入与实际系统相同的控制和环境参数,比较两系统输出的飞行参数,相减得到基本平稳的误差序列,然后对该序列进行时间序列建模,并分析建模结果的稳定性,从而检测出飞行仿真系统的精度。实验表明,该方法能够有效检测仿真系统的精度。

Flight system simulation experiment can be used to test the performance of the plane. In order to guarantee simulation test process reliable and correct, the simulation precision need be tested firstly. Time series modeling analysis is feasible for that. The same control and environment parameter values to practical system were input to the simulation system, their output parameter values were compared and obtained the difference value series which was modeled by time series modeling, and the stability of modeling was analyzed. Then it was judged whether the precision of the simulation flight system meat the precision demand or not. The experimental results indicated that the approach can detect the precision of the simulation system effectively.
