小卫星大角度姿态机动控制研究及半实物仿真验证

大角度姿态机动控制技术是高分辨率遥感小卫星的关键技术之一。本文采用瞬时欧拉轴控制算法，在星载计算机原理样机的基础上，考虑反作用飞轮的饱和特性，根据所选择的反作用飞轮和光纤陀螺，在单轴气浮转台上进行半实物仿真验证。仿真结果表明，所设计的定姿与控制算法简单、有效；星载计算机满足控制算法对计算速度的要求。

The Research and Semi Physical Simulation of Large Angle Maneuver Attitude Control for Small Satellite

Large angle manetwer control technique is imporlont for the small satellite, this paper discussed the mstoataneous - turn - axis control arithmetic. We have finished the semi - phsical simulation on the single axis turfing platform, which included on board prototype computer, optic fiber gyro and reocaon wheel which saturation chamaeristic has been taken into account. The results indicated that the control arithmetic has the advantage of simplicity and efficiency, and the on board prototype computer could satisfied the requirements of the operating speed.
