摘　　要：文中直接以结构的动力学变量作为系统状态，从理论上推导出了反馈和状态变量的解析表达式。基于该表达式，对一空间站模型进行了仿真。结果表明，该方法具有计算量小、稳定性好的优点，便于在线控制。Using multilevel control method, we studied the coupling active control of the large flexible structures in this article. Taking the dynamic variables of structure as the system states directly, the feedback gains of this vibration system have been developed. According to the theory presented in this article, one space station model has been taken as an illustrated example. The computer simulation has been carried out and the satisfactory results have been gotten. Theoretical and numerical results show that the method presented in this article is of many spedal advantages to the vibration system of large flexible structures.
