摘　　要：回顾了时滞滤波器的发展背景和近年来的研究状况 ,介绍了时滞滤波器的各种设计方法和主要研究领域。时滞滤波器可从根本上避免激发对象的振动模态而消除残留振荡 ,在柔性结构系统中得到了广泛的应用。最后对时滞滤波器技术中存在的问题及未来的研究方向进行了探讨。Review of the development of time delay filter is presented. Firstly, the concept and essence of time delay filter are given out. Time delay filter is a method for reducing residual vibrations in computer controlled machines. Vibration is eliminated by convolving a sequence of impulses with a desired system command to produce a shaped input. Then, important research fields of time delay filter are mainly divided into seven parts, including new design method, optimal time delay filter design, nonlinear and adaptive time delay filter. Time delay filter technique is applied to mechanical structure with flexible modes widely. Finally, several problems pending further investigation are discussed.
