二维弹道修正引信制动控制建模与仿真

为解决二维弹道修正引信滚转姿态实时控制问题，提出了固定舵制动模型。根据弹道修正原理及固定舵控制规律，建立了制动控制数学模型。构建了基于双轴仿真测试转台的半实物仿真系统，对不同弹道环境下制动控制性能进行了半实物仿真。结果表明干扰力矩在0～0.5 N · m变化范围，该方法能够有效跟踪滚转角控制指令实现实时跟踪。当弹丸转速在100～167 r／s范围时，该模型制动时间和精度满足控制系统总体要求。

Braking Control Model and Simulation for Precision Guided Kit

To solve roll attitude real-time control problem for a 155 mm canard guided dual-spin stabilized projectiles , braking control model was proposed .According to trajectory correction theory and canards braking principle , the trajectory braking control model was given .The semi-physical simulation system was set up based on tow-axis flight simulation table , which can drive the dual-spin stabilized projectiles at different roll rate.The results show that braking model can rack roll attitude control-instruction under condition of 0.5 N· m disturb mo-ment , and the nose portion can brake accurately at control roll attitude when the projectiles rotate at 100 r/s to 167 r/s.The braking preci-sion and duration time can fulfill the need of guidance and control system .
