| Abstract: | An approach to
implement Modal Filters (MF) with closed or repeated frequencies as those of space
intelligent truss structures is proposed in the paper. Based on MF and time-sharing which
uses controllers effectively, a control strategy of Independent Modal Space Control (IMSC)
is developed for the active vibration suppression of space intelligent truss structures.
Simulations demonstrate that it is effective and feasible. |
