摘要: 本文研究刚体-挠体互联的空间结构的旋转操纵,针对挠体的建模参数存在误差的情况给出控制律。为此,本文从Lyapunov稳定性理论出发推导了不定系统的鲁棒控制方法,构造了针对参数不定性,外界输入不定性的控制规律。仿真结果表明该控制规律实际有效。

Abstract: This paper deals with the slewing maneuver of flexible space structures. The robust control rule is given for the linear systems with parameter uncertainty. The robust control is based on the Lyapunov' s theory of stability. Three kinds of control law are given in the forms of the linear control, nonlinear control with matching condition, and nonlinear control without matching condition, respectively. The robust control method is applied to the slewing maneuvers of Flexible Space Structures, and the simulation results prove that the robust control is effective for the Flexible Space Structures with parameter uncertainties.
