| 摘 要： | 为了研究鸭式布局有控弹药控制过程中攻角变化的动态过程,寻求合理的舵控方式,以一对鸭舵控制的炮弹为例,引入常用的舵控波形,建立了六自由度刚体有控弹道模型,研究了鸭舵控制对复攻角运动的影响,推导了简化的控制传递函数,用于分析各弹道特征点上气动参数变化带来的影响.数值计算和MATLAB建模仿真表明,采用最大周期平均力时鸭舵的控制效率最高,但也会引起攻角的强烈震荡,不适于弹药稳定性要求较高的情形.

| Abstract: | In order to research dynamic process of the attack angle for controlled projectile under canard control,and seek the better control mode of the canard,taking the shell with a pair of canards for example,a 6-DOF(degree of freedom) rigid trajectory model with canard control is built to research the effect control progress of the attack angle.The control transfer function is deduced for predigesting analysis in feature points.The numerical calculation and simulation by MATLAB show that the maximal average forc... |
