摘　　要：针对空间智能桁架等密频结构 ,提出了一种适应性较好的模态滤波器的实现方法 ,基于模态滤波器和分时共享充分利用作动器的思想 ,采用独立模态空间控制方法 ,实现了空间智能桁架结构的振动主动控制。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.
