| Abstract: | 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. |
