摘　　要：为增强修正弹控制舵的快速响应能力和弹道修正效果,且理论上减弱舵片在高旋状态下对弹体的气动扰流影响,设计一种控制舵置于质心后部、与弹尾部高度配合的新型二维修正弹。建立弹体模型,设计以优化后的新式制导方案和比例微积分控制法为主体的组合控制策略,分析无控和有控状态下关键变量参数的变化规律,对基于参数最优值下的弹道修正过程进行仿真计算;采用蒙特卡洛打靶法分析扰动状态下的落点散布情况。仿真结果表明:此控制策略下后舵尾控弹的实际滚转角吻合于输入指令,整个过程速度高低角和方向角的变化范围仅为2°和7°,基于最优值的控制修正过程和扰动状态下的最终落点情况也保证了弹体进行平稳运动的同时具备更优的偏差修正能力,进一步证实了设计的新型弹体模型具有较高的可行性和参考价值。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.
