摘要
针对某型卫星地面半物理仿真实验,提出一种新型解耦方法,解决在三轴转台的中框旋转至90度附近时,内框与外框重合导致出现奇异性的问题。从角度变换公式入手,分析出现奇异的原因,并对新型方法进行计算、仿真。结果表明,在不能避免三轴转台内框与外框重合的情况下,在以保证三个轴的转速不超出转台最大速度限制的条件下,可以满足卫星的半物理仿真实验要求。
In allusion to the satellite attitude and orbit control semi-physical simulation system, a new decoupling algorithm of the turntable was put forward, which solved the singular problem caused by the overlap of middle frame and outer frame when inner frame turn to 90 degrees. Started with the angle reforming formula and figured out the reason of singular phenomenon, calculated and simulated the novel method. The result showed that when the overlap of middle frame and outer frame is unavoidable, the requirement of semi-physical simulation was satisfied in the case of unexceed the speed limit of three axes.
