讨论航天器太阳帆板展开过程中主体姿态的最优控制问题．在控制算法中利用小波分析理论，将离散正交小波函数引入最优控制问题，利用小波展开法替代传统的Ｆｏｕｒｉｅｒ基函数，提出一种基于小波分析的最优控制算法．数值仿真结果表明，小波展开法对太阳帆板展开姿态控制问题是有效的 Discusses the optimal attitude control of the main attitude during spacecraft solar panel deployment. In the control algorithm using wavelet analysis theory, the discrete orthogonal wavelet function is introduced into the optimal control problem, and the wavelet expansion method is used to replace the traditional Fourier basis function. An optimal control algorithm based on wavelet analysis is proposed. The numerical simulation results show that the wavelet expansion method is effective for the attitude control of solar panels.
