doi:10.12382/bgxb.2023.0178

Abstract

Abstract:

In order to enhance the response ability and trajectory correction effect of trajectory correction projectile’s control rudder and greatly reduce the aerodynamic turbulence influence of rudder on the projectile body in theory, a new type of two-dimensional trajectory correction projectile,in which the control rudder is placed behind the center of mass and can be highly matched with the tail of the projectile,is designed.A projectile body model is established, and a composite control strategy with the new optimized guidance scheme and proportional calculus control method as the main body is designed.The change law of state variable parameters in the uncontrolled and controlled states are analyzed, and the trajectory correction process based on the optimal values of parameters are simulated; Monte Carlo method is used to analyze the dispersion of impact points under the disturbance state. The simulated results show that the actual roll angle of tail rudder controlled projectile is basically consistent with the input command under this control strategy, and the change ranges of speed angle and direction angle in the whole process is only 2° and 7°, respectively. The control correction process based on the optimal values and the final impact point in the disturbance state also ensures that the projectile body can move smoothly and has better deviation correction ability, which further confirms that the designed new projectile model has high feasibility and reference value.
