摘　　要：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。The optimal attitude control probl em of spacecraft during its solar arrays stretching process is discu ssed in the present paper. By usin g the theory of wavelet analysis i n control algorithm, the discrete orthonormal wavelet function is in troduced into the optimal control problem, the method of wavelet exp ansion is substituted for the clas sical Fourier basic function. An o ptimal control algorithm based on wavelet analysis is proposed. The effectiveness of the wavelet expan sion approach is shown by numerica l simulation.
