卫星姿控仿真系统中的力矩传感器

TORQUE SENSOR USED IN A SIMULATION SYSTEM OF A SATELLITE ATTITUDE CONTROL

在卫星姿态控制半物理仿真系统中 ,执行机构飞轮的输出力矩多采用通过对飞轮转速度化的计算来获得。本文提出一种基于力反馈原理的力矩传感器 ,用它对飞轮输出力矩测量 ,其性能指标明显优于上述方法。从有关实验结果看 ,一个精度高于 0 0 0 0

In the satellite attitude control semi physical simulation system,the output torque of the fly wheel in the executive unit is mostly obtained by computing the its velocity change.We developed a torque sensor based on torque feedback principle.It has a better performance than the methods above;and from the result of relevant experiment,the torque sensor with higher accuracy than 0 0005N·m can be manufactured.
