| Abstract: | In this paper, the small-loop theorem and functional analysis are used to analyse the stability of LQG modal control systems of flexible spacecraft, and a sufficient condition for control systems to keep in stability under influence of residual modal is given, and the estimation of errors diviated from the ideal output under influence of residual modal is also presented. |
