中文摘要

      振荡控制是指通过引入零均值的高频振荡信号来改善系统动态特性的方法. 本文对振荡控制理论的研究现状进行了回顾, 总结了振荡控制近年来的研究成果, 指出了该理论在研究中存在的问题和研究方向, 最后探讨了它的发展前景. 振荡控制在某些状态或输出难以测量、反馈控制难以实施的系统控制中不失为一种比较优秀的控制方法.

英文摘要

      Vibrational control is referred to the effect of changing the properties of dynamic systems caused by introduction of high_frequency vibrations with zero mean value. This paper reviewed the research status of vibrational control technique. The main theoretical and application results as well as achievements of vibrational control are concluded, also the problems existing in current vibrational control study along with the research directions for furture are pointed out. Finally, the development prospect of vibrational control is discussed. It is shown that the vibrational control is an excellent method in case where the traditional techniques fail to be used.
