结构振动的独立模态和耦合模态的组合控制

基于模态空间控制的基本原理，提出了一种将独立模态控制与耦合模态控制相结合应用于结构振动主动控制中，得以利用两者的优点而使控制更加有效和稳定的方法。利用该组合控制法，可实现在一个控制过程中实时跟踪主被控模态的变化从而对其实施独立模态控制以达到有效地抑制结构的主要振动。而对其它非主控模态则实行耦合模态控制。这样，可使控制系统的稳定性提高、减少作动器／传感器的数量、降低控制能耗，并能在不同的激励下达到最佳的控制效果。

Hybrid Method of Independent and Coupled Modal Space Controls for Intelligent Structures

Based on the basic principle of modal space control,a new method of combining independent and coupled modal space controls to form a faster and easies controlling approach is presented,which has the advantages of both independent and coupled modal space controls,and has the ability to follow the varying of structural main vibrating modes and control them with more efficiency.The control of more than one mode in system can be realized by using fewer actuators with excellent performance features and satisfactory specified stability.The simulation results prove the efficiency of the approach proposed.
