Derivation of dynamic model and simulation of guided munitions

In this paper, a six degree-of-freedom dynamic model of guided munitions is derived. On the assumption that itpsilas a rigid body, the effects of wind are taken into consideration, both constant wind velocity and wind acceleration respectively. Compared with traditional models of guided munitions, the time change rates of angle of attack and angle of sideslip are explicitly expressed in this model. Uncontrolled simulation based on this model in the Matlab/Simulink environment is performed, the results show that this model is valid and practical.
