Decoupling Sliding Mode Control in A Nonlinear Spacecraft System
-
摘要: 提出了非线性空间飞行器系统采用滑动模态控制方法,它对强非线性的空间飞行器系统通道间交叉影响进行解耦. 在大的参数变化和外干扰下,解耦空间飞行器具有优良的鲁棒性.它的姿态稳定和机动飞行控制的数字仿真支持了本文结果的有效性.Abstract: A control method with sliding mode of nonlinear spacecraft system is provided in this paper, in which the interactive influences among channels of strong nonlinear spacecraft system are decoupled. The decoupled spacecraft with large parameter variations and external disturbances is of good robustness. The numerical simulations of its attitude stability and maneuver control give support to the effectiveness of results in this paper.
