Attitude model identification of small satellites with missing data

This paper applies the wavelet reconstruction technique to the identification of attitude model of small satellites when there exists missing phenomenon in the input or/and output experiment data. Two kinds of missing data existing in the satellite attitude control systems, namely, the multirate case and the random missing type are both considered. By employing the wavelet analysis, two corresponding identification algorithms are respectively proposed under the condition of these two kinds of missing measurements. Finally, the simulations and comparisons are given to verify the effectiveness of proposed methods.
