旋转导弹单通道控制方法研究

通过分析旋转导弹的控制原理 ,从弹体舵面产生的周期等效控制力与导引头输出的误差信号之间的方位误差和幅值线性度两个方面 ,提出了一个最优的线性化信号与主控信号的频率比。建立了刚体弹道仿真软件 ,以某型防空导弹为背景进行了一系列的仿真计算。仿真结果表明 ,这一最佳频率比大大提高了导弹的制导精度 ,减小了脱靶量。

Study on single-channel control for rotary missile

In this paper, an optimal frequency ratio of linearizing signal to control signal is presented, with the bearing error and magnitude linearity between the periodic equivalent control force produced by steering engine and bearing error signal from the seeker considered, by means of analyzing control operation of self rotating missile. Based on it, the rigid trajectory simulation software is written. A great deal of simulation for rigid trajectory has been done on a given missile. The simulation results show that the optimal frequency ratio to some extent greatly improves the guidance precision and reduces the trajectory miss distance.
