| 摘 要： | 针对传统法解决转台解耦问题存在的不足,将欧拉角速度转为陀螺角速度,地球自转作为转动激励,提出了一种新的转台解耦方法。对框角解耦算法以及卫星三轴与转台三轴不同关系条件下的转台改进算法进行了仿真。结果表明:用转台模拟卫星欧拉姿态角时,应尽量避免中内框夹角过小;卫星稳态运行时,转台的内外框分别模拟卫星的俯仰、偏航轴。转台不会产生接近奇异的现象。

| Abstract: | In allusion to the deficiency of tradition which resolved the problem of turntable decoupling algorithm,a new decoupling algorithm of the turntable was put forward,which converted the Euler angle velocity to gyro angle velocity and the earth rotation was severed as the stir in this paper.The simulation was carried out for the frame decoupling algorithm and turntable improving algorithm under the condition of different relations among three axis of the satellite and the turntable.The result showed that over small included angle of mid-inner frame should be avoided as far as possible when satellite＇s Eular attitude angle was simulated by turntable.The turntable generated no any near singular phenomenon simulation when the pitching angle and yaw angle were simulated respectively by turntable＇s inner and outer frames in the steady state operation of satellite. |
