The Modeling and Forecasting of the Successive Test Data Time Series for SIMU
Qian Pei-xian · Journal of Projectiles.Rockets.Missiles and Guidance · 2005
The successive test data analytical method of SIMU (Strapdown Inertial Measurement Unit) is introduced.Ai- ming at small sample,and the difficulty of small sample model building,the double-modified-interpolation method is presented to establish the time series which is needed for model building.It is a very useful way to solve the problem of small sample model building for SIMU.Finally.using the time series forecast,the changing tendency of error coeffi- cient is forecasted.This method gives the theoretical help for using,analyzing and selecting SIMU.
