Timoshenko梁振动的模态控制方法

Vibration Control Analysis of a Timoshenko Beam

摘要:

分析了Timoshenko梁振动特性,得出其简化模型及其在外力作用下的传递函数,然后分析了压电材料PZT对梁振动的作用,得到它的传递函数。设计控制系统并分别设计人工神经元网络辨识器及其控制器,给出振动控制系统的仿真结果并进行分析。

Abstract:

Firstly, the vibration characters of Timoshenko beam which mounted by PZT were analyzed and a simple model for it was given. Then the vibration modes were analyzed based on this simple model. At last a control system using the neural network method was presented, and the characteristics of the system were simulated numerically by MATLAB.
