基于PPF的柔性悬臂梁主动振动控制

Flexible Cantilever Active Vibration Control Based on the PPF Algorithm

研究空间结构中悬臂梁的主动振动控制。首先使用PPF(Positive Position Feedback)的主动振动控制方法,得到和一般负反馈相比相对优化的脉冲响应,再利用结构频率与特征方程根的关系进行最优化参数选取,最后进行仿真。仿真结果表明基于PPF方法主动振动控制能够很好地实现对悬臂梁结构的振动控制。

This paper studies the active vibration control of the cantilever in space structures. First, positive position feedback （ PPF） active vibration control method was used, and getting better pulse response compared to the general negative feedback. Second, the optimal parameters were selected using the relationship between structural frequency and the roots of the characteristic equation. Finally simulation was carried out. Simulation results show that PPF active vibration control methods can achieve a good vibration control for the cantilever structure.
