垂直发射弹药脉冲发动机转弯控制方法

The Control of Vertical Launch Missile Turning with Pulse Engine

垂直发射弹药在初始飞行段速度较低而经常利用侧向脉冲发动机产生直接力控制弹体转弯。为解决初始扰动较大情况下如何控制弹体快速精确转向指定方位的难题,文中以某垂直发射弹药为背景,定义了一种角速率投影相等的新弹体坐标系,再将目标空间方位投影到新定义的弹体坐标系,最后根据误差角投影大小,利用逻辑运算得到脉冲发动机点火指令。仿真结果表明,文中所述转弯控制方法的控制效果良好。

In view of the slow speed at the initial flight section,the vertical launch missile usually uses the lateral pulse engine to produce the direct force to control the turn of missile body.In order to solve the problem of how to control the missile body to turn to the appointed orientation rapidly and precisely under the condition of larger initial disturbance,this thesis,on the background of X-type vertical launch ammunition,defines a new missile-body coordinate with equal angular velocity projections,and then projects the target spatial orientation to the newly-defined missile-body coordinate.At last,the ignition instruction of pulse engine is calculated by logical operation based on the size of error angle projection.The simulation result shows that the contr ol effect of the turning control method mentioned in the thesis is fine.
