摘要:

对一个带有压电铺层的悬臂层合板进行了振动主动控制的分析和试验。不但采用了速率反馈 ,还用现代控制理论的设计方法研究了最优控制问题 ,设计了相应的数字式控制试验系统 ,进行了试验验证 ,并对 2种控制律的结果进行了比较。同时还研究了机电耦合刚阵的影响。

Abstract:

Analysis and experiments of the active vibration control to a plate with piezoelectric actuators are summarized. Both velocity feedback and linear quadratic Gauss(LQG) control were analyzed and tested. Digital control systems were designed and tested. Calculated and tested results are compared. The effect of mechanical electric coupling was also investigated.

Key words: piezoelectric actuator, coupling of mechanics electricity, damping, velocity feedback, optimal control
