| 摘 要： | 细长体双自旋卫星自旋部分的能量耗散会导致卫星章动运动的发散。利用消旋体的惯性积在动力学上的耦合作用,使消旋电机的轴向力矩通过耦合,产生横向力矩来阻尼章动,称之为消旋主动章动控制（ＤＡＮＣ）［１］。本文提出一种利用动力学解耦的仿真方案,用单轴平台进行细长体双自旋卫星消旋和章动控制的系统试验,验证了系统的可行性。

| Abstract: | Passive energy dissipation existing in the spinner of prolate dual-spin satellite will lead to nutation divergence. Using the inertia product provided by the despun platform,a transverse torque which is normal to spin axis is produced through the dynamic coupling between the nutation dynamics and the despin platform control system, thus achieving "Despin Active Nutation Control(DANC)1]". This paper presents a dynamics decoupled simulation method in which a single-axis spin platform is employed to simulate dual-spin satellite despin and nutation control system performance using decoupling between the nutation dynamics and the despin control.And system feasibility is verified. |
