摘　　要：首先基于哑铃模型建立空间系绳系统的数学模型,然后对标准系数法进行了介绍,在此基础上提出了基于标准系数法的空间系绳系统状态保持稳定控制算法,最后结合仿真实例对空间系绳系统的状态保持稳定控制进行了分析,并与线性最优二次型设计方法进行了比较,同时还对系统的鲁棒性进行了研究。结果表明使用标准系数法设计的控制系统不仅能够达到控制要求,而且设计简单,所得出的控制系统具有良好的鲁棒性。Firstly, the mathematical model of space tether system based on the dumbbell-shaped model is established. Then, the standard coefficient method is briefly described, and detailed discussion follows on how to design the controller. Finally, by employing simulation cases, the steady control of space tether system is analyzed, and also simulation results are given by comparing the method proposed in this paper with the well-known linear quadratic regulator method. At the same time, the robustness of the control system is studied. The simulation results show that the controller based on the standard coefficient method can achieve the requirement of control system while it is simpler than the linear quadratic regulator method and the control system also has good robustness.
