摘　　要：从振动主动控制系统的振动能量和控制能量的角度出发，应用最优控制理论，对智能柔性结构振动主动控制中驱动器的最优配置策略进行了研究，给出了相应的控制规律。为了获得最佳的控制效果，引入了改进的基因遗传（ＧＡ）算法，并以悬臂梁为例，讨论了压电驱动器的位置、数量、配置方式以及控制增益对智能柔性结构振动主动控制效果的影响，为智能梁的结构设计奠定了理论基础。From the view of the energies of vibration and control in vibrating structures controlled actively, the optimal disposition of actuators in intelligent flexible structures is studied on the basis of optimal control theory and the corresponding control law is proposed in the paper. The general Genetic Algorithm (GA) is improved properly in order to obtain the best control effect. A cantilever beam, as an example, is taken to demonstrate the approach, and the influence of the numbers, locations, the ways of disposition of actuators and control gains on the active control in intelligent beam structure are discussed in the paper.
