摘要
为扩大绳系卫星系统(TSS)控制的稳定域,提出了一种改进距离速率控制算法。根据TSS动力学方程及构造的二阶稳定系统,给出了修正的控制模型。讨论了稳定释放角度和释放/回收速度的影响,并研究了固定绳索长度系留控制方案。算例表明该方法可显著扩大稳定域,提高释放速度。
To enlarge the stability area of tethered satellite system＇ control, a modified range rate control law was put forward in this paper. According to the dynamics equation for tethered satellite system and two-order stability system established, the modified control law was presented. The effect of stable release angle and release/recoil rate was discussed, and the tethered control scheme with tether length fixed was studied. The simulation results showed that the modified control law could expand the stable control area greatly and speed the release.
