| 摘 要： | 针对单轴定向大气层外拦截器设计了一种姿态控制律。拦截器简化为轴对称刚体,利用安装在弹体尾部的“＋”形组合六喷嘴发动机提供控制力矩。由于姿控系统难以同时进行偏航和滚动控制,根据拦截器单轴定向体坐标系不唯一的特点,通过合理选择目标坐标系实现了偏航和滚动通道的分时控制。设计了姿控发动机开关控制律．分析了系统在控制律作用下的稳定性并进行了仿真验证。

| Abstract: | An attitude control law for single axial direction control of an exoatmospheric interceptor is put forward. The interceptor is assumed to be an axial symmetry rigid body, using engines fixed at the back of the body with six nozzles collocated in "+" shape to supply the control moment. A time-sharing scheme is designed by properly defining the desired body coordinates, since it is hard for the attitude control system to supply control moment in yaw and roll channels simultaneously, based on the characteristics of the single axial direction control that the body coordinates with one axis pointing to the desired direction is not unique. The on-off control law is designed, the stability of the system is analyzed and validated by simulations. |
