| 摘 要： | 提出了一种航空遥感器扫描反射镜姿态控制的新方法,用小型、低造价的线性加速度计代替陀螺感测飞行器的三维角运动,反射镜姿态控制系统用实测的角加速度作为控制系统的反馈信号.根据用线性加速度计指示角加速度的公式,讨论了将加速度计直接配置在扫描反射镜镜体上的方案,并给出了执行扫描反射镜姿态控制策略的控制系统原理图,证明该方法在理论上是简易可行的,具有一定的实用性.

| Abstract: | A new control approach of aero remote sensor scanning mirror is discussed in this paper,where miniature,low-cost,linear accelerometers are used to sense three-dimensional angular motion instead of gyros.The servo system used the measured angular accelerations as feedback signal to control scanning mirror pose.According to the formula,which shows the angular acceleration through linear accelerometer,the case that the accelerometers are placed on the mirror body is presented,and the sketch map of control system is given.Which proves this method is feasible,simple and convenient. |
