| Abstract: | A physical and mathematical model is developed for describing nitrogen launching system(NLS)based on the dynamics of pneumatics and mechanisms.The multi objective optimization function for the pitching angle and velocity of a missile was proposed for the first time.Singularity detection of wavelet analysis was conducted to find the optimum iteration points in a new direct algorithm of non linear programming.Comparison between wavelet optimization and complex method show that the former is better for optimization design. |
