For the aerodynamic parameters identification of projectile and rocket under the influence of random wind, based on the control system sensitivity theory, the formation of the sensitivity and related mathematical models according to realistic systems are formulated. Sensitivity principle of the control system theory is applied to the identification of resistance coefficient. Analyzing missile system...
Trajectory correction fuze is the integrated guidance and control and the new fuze technology which can correct trajectory through the fuze. In order to improve solution precision for trajectory correction fuze, a resistance coefficient identification method based on the sensitivity theory of control system is put forward. Combined with test data of the ballistic parameters, resistance coefficient...
Random wind is one of the important factors causing rocket fall points distribution. For the large and complex system, it is difficult to analyze the reliability using the analytic methods, but the computer simulation is an effective way. In this paper, simulation for flight control system is studied in detail by considering wind as typical random process. The engineered model of wind is established...
In the flight of cannonball and rocket, due to various random factors the ballistic dynamic parameters in the flight dynamics model will occur randomly. Based on sensitivity function theory of control system and taking the angle movement into account, the algorithm of the sensitivity of the ballistic parameters for the aerodynamic parameters is brought out. In the same time, the degree of aerodynamic...
