Adaptive feedback control method for active vibration isolation based on on-line frequencies estimation

  • 摘要: 针对自适应前馈控制方法的缺点,提出一种周期性振动主动控制的自适应反馈控制方法.利用误差信号恢复振动干扰信号,采用级联陷波器估计信号中周期性分量的频率,并在估计频率处为控制器构造参考信号;控制器的参数则根据Lyapunov稳定性原理进行调整.仿真和主动隔振试验结果表明:频率估计方法在不同信噪比情况下均具有较好的估计精度;主动控制方法在振动频率处的隔振效果明显,隔振量可达16 dB以上,且控制器的参数收敛速度较快.
