Prediction on Aircraft Flight Simulation Data Based on Improved Grey Model
In order to solve the real-time problem in simulation,this paper proposes a grey prediction model to predict the simula-tion data,and improve the simulation speed and practical application of grey model in the prediction on simulation data;Cubic spline interpolation is used to interpolate non-equal time interval sequences to obtain equal time interval sequences;The background value calculation process is improved during the modeling process of grey model;The idea of metabolism is combined in the updating data,weakening the old data,and strengthening the influence of new data on the model;The grey model is connected to be verified on the aircraft distributed virtual simulation platform.The verification results show that after the improved grey prediction model is connect-ed to the simulation platform,it has a better performance and can accelerate up to 8.9％.
