摘　　要：研究压电智能简支梁的振动主动控制。通过分析简支梁在受到外部激励后,梁中点的振动过程,建立一个符合梁中点运动过程的模糊控制规则。采用以梁中点的位移和速度为输入变量,对梁施加的控制力为输出变量的方法,设计一个模糊控制器。通过使用Matlab对此过程进行仿真实验,结果表明采用这种方法能够更有效的控制简支梁的振动。This research aims at the active vibration control for intelligent simple beam. Fuzzy logic control rules are established based on the analysis of the motion traits of simply supported beam. Based on the tradition fuzzy logic controller, the paper proposes a new fuzzy control strategy, which uses the displacement and the velocity of cantilever beam tips as inputs, and the control force on cantilever beams as outputs. Simulation experiment has been done by the use of Matlab and the results have proved that the proposed method is a much more efficient way in the vibration control of beam.
