Modeling and Simulation of the Interceptor by Combined Control of Lateral Thrust and Aerodynamic Force

Nonlinear dynamic model and kinetic model are constructed based on the moment of momentum theorem for the interceptor by combined control, and a model of the impulse motor is presented. These models can precisely describe the motion of the interceptor when the interceptor is controlled by combined control and aerodynamic force, respectively. A model of the relative movement between the target and interceptor is also constructed, which is useful to control interceptor and is convenient for the practical project. The simulation results show that these models have satisfactory control precision for small or large attitude maneuver of the interceptor, and have satisfactory guiding precision for non-maneuverable or maneuverable target also, which shows the veracity and advantage.
