摘　　要：以粘贴有压电传感器与执行器的智能悬臂梁的动力学模型的振动方程与传感方程为基础,分析了基于此智能悬臂梁结构的最优控制理论与方法,设计了用于仿真的控制率,最后通过对阶跃与正弦信号激励下的智能悬臂梁的MATLAB仿真,证明对于该结构的最优控制方法是行之有效的。Based on optimal control system,the model and active vibration control method of piezoelectric smart cantilever beam were researched. In this research ,control method for simulation was designed. With MATLAB software ,the responses of the beam model system were simulated with step and sine signals. The results show that the control method is effective.
