A new methodology for simulation validation and model modification

In this paper a new method to combine the matching measured flight response, simulation validation and model modification is introduced. For the flight system with the nonlinear motion equation. Using the test data and the simulation results, the Error Data Base(EDB) is obtained with optimal method. The validation for the simulation model and the criterion is given. The modified simulation model is formed with EDB. Finally some simple examples are made to verify the metthod. The results are satisfactory.
