自旋导弹控制方法的研究

Study on control for self\|rotating missile

通过分析自旋导弹的控制原理，提出了一种高精度控制方法，消除了模拟驾驶仪线性化处理过程引入的误差。建立了数字驾驶仪和刚体弹道仿真软件，以某型防空导弹为背景进行了一系列仿真试验，仿真结果表明，数字驾驶仪改善了弹道特性，减小了脱靶量，尤其在对低空近距离目标的攻击效果更为明显。

In this paper, a method of higher accuracy control to self\|rotating missile is presented by means of analyzing control operation, so that error in linearization processing for analogue autopilot has been easily eliminated. Based on it, the mathematical model of digital autopilot is set up, and the rigid trajectory simulation software is written. A great deal of simulation for rigid trajectory have been done based on a given antiaircraft missile. The simulation results show that the digital autopilot can greatly perfect the trajectory property, and reduce the trajectory miss distance. Specially, it can greatly raise the missile attack effectiveness to low\|altitude short\|range target.
