采用现代模态滤波器（ＭＦ）技术和最优控制理论研究智能空间桁架结构的独立模态空间控制方法（ＩＭＳＣ）。仿真结果表明，按提出的控制策略，解决了传统ＩＭＳＣ控制中的状态解耦问题，使ＩＭＳＣ方法不再局限于简单、低自由度数的结构动力控制，对于智能空间结构，实施ＩＭＳＣ方法也是可行并且有效的。
The modern mode-controlled filter (MF) technique and the optimal control theory are used to study the independent modal space control method (IMSC) of smart space truss structure. The simulation results show that according to the proposed control strategy, the state decoupling problem in traditional IMSC control is solved, and the IMSC method is no longer limited to simple and low-degree-of-freedom structural dynamic control. The implementation of IMSC method is also feasible for intelligent spatial structure Effective.
