柔性梁的振动主动控制研究

对柔性梁的振动分析方法进行了研究。运用系统的分析方法对柔性梁的振动进行分析,并建立柔性梁的动力学系统模型。输入信号通过最优控制理论的计算输出最优控制信号作用于执行器产生相应的执行力来抑制柔性悬臂梁的振动,从而达到对振动进行控制的目的。通过仿真结果表明,采用主动控制器来抑制柔性梁的振动是非常有效的。

Study on Flexible Beam Vibration Control System

The methodology of vibration evaluation of Flexible Beam is researched in this paper. The flexible beam vibration is analyzed by method of system; The dynamical equation of the flexible beam is set up. Through the optimal control theory,it is applied to the actuator in the process of the vibration input signal and output optimal control signal so as to control the vibration resulting in corresponding implementation to suppress vibration of the beam. The simulation results show that the controller is very effective for improving the vibration speed control.
