Modeling and Control of the Interception Missile by Combined Control of Lateral Thrust and Aerodynamic Force

The model of attitude motion is established for the interception missile by combined control of lateral thrust and aerodynamic force in aerosphere.A switching model of the interception missile is constructed by hybrid automaton,then switching rule for control system and control law for lateral thrust are presented.This method shows the switching between different states of interception missile,which is useful to control the interception missile and is convenient for the practical project.The simulation results show that this method can realize the attitude adjustment of the interception missile effectively in the case of economizing impulse motors so as to prove the validity and advantage of the method.
