在这项工作中，提出了两种特殊的高增益跟踪微分器。通过采用一种基于泰勒展开的巧妙技术，有效地减小了传统高增益微分器的时滞现象。因此，所提出的微分器的微分精度远高于传统的高增益跟踪微分器。
In this work, two special high-gain tracking differentiators are proposed. By using an ingenious technique which is based on the Taylor expansion, the time lagging phenomenon of the traditional high-gain differentiator is reduced effectively. Therefore, the differentiation exactness of the proposed differentiator is much higher than that of the traditional high-gain tracking differentiator.
