根据最优控制理论，通过对多点力矩型作动器位置的仿真研究可以看出：力矩型作动器在柔性结构上的最优位置呈区间分布，便于工程实现；基于最优控制的最佳力矩型作动器位置配置能显著地衰减柔性结构的低频振动，且只需要很小的控制作用．
According to the theory of optimal control, through the simulation study on the position of multi-point moment actuator, it can be seen that the optimal position of moment actuator in the flexible structure is distributed in intervals, which is convenient for engineering implementation. Based on the optimal control Good torque actuator position configuration can significantly attenuate low-frequency vibration of the flexible structure, and requires only a small control.
