Spectral analysis and parameter selection for BCB attitude maneuver path of flexible spacecraft

Abstract

The classical Bang-Coast-Bang path spectrum was analyzed by FFT in order to select the path parameters which were fit for flexible spacecraft attitude maneuver. Spectrum expression of BCB path was derived by means of DFT. The relation between the path parameters and spectrum as well as maneuver time was studied by analyzing the spectral characteristics of BCB path. A selection method of BCB path parameters was proposed. Research results indicate that if the BCB path parameters are selected by the proposed method, it can effectively reduce flexible appendages' vibration affected by attitude maneuver for rapid maneuver and rapid stabilization. Numerical simulations demonstrate the effectiveness of the method, and it is useful for BCB path parameters selection.
