引信滚转角双闭环控制算法

摘要

“精确制导组件”(PGK)是目前较为先进的二维弹道修正引信方案,滚转控制算法是其关键,但是相关资料中未见报道,为此提出引信滚转角双闭环控制算法.该算法根据实测气象条件计算引信所受的导转力矩；以实测滚转角与目标滚转角的位置为依据,计算引信需要转过的角度,结合实测的滚转速度信息,计算需要作用在引信上的电磁力矩；引信受到电磁力矩作用后实际滚转姿态与滚转速度可由姿态测量模块解算得到,并作为反馈信息代入下一时刻的实测滚转角和滚转速度,更新输出的电磁力矩,形成双闭环的控制系统,使得系统总是可以输出合适的电磁力矩,以达到控制引信滚转姿态的目的.仿真结果表明,该控制算法能够满足二维弹道修正对引信滚转角控制的要求.%PGK is an advanced two-dimensional trajectory correction fuze scheme,and roll control algorithm is the key factor of it,but relevant information was seldom reported.Aiming at 2-D trajectory correction fuze roll angle control problem,a roll angle double closed loop control algorithm based on the roll angle position and velocity feedback was put forward.On the basis of the goal of fuze angle,the actual roll angle and roll rate,the needs of applied electromagnetic moment could be calculated.When fuze roll attitude changed in this moment,the feedback information was formed by measuring device.Then a double closed loop control circuit was set up and ultimately it would achieve fuze roll attitude control purpose.The simulation results showed that the control algorithm could meet the 2-D trajectory correction fuze roll angle control requirements.
