在较弱的条件下，研究了一个线性跟踪微分器跟踪干扰信号并提取其微分的问题。首先，应用特征根法得到跟踪微分器系统的解。其次，利用Riemann引理对跟踪信号的收敛性进行理论证明。最后，通过数值模拟论证了跟踪微分器能够有效地跟踪微分信号。

In this work ,a linear tracking‐differentiator is applied to extract differential signal from the corrupted input under a weaker assumption .Firstly ,the eigenvalue method is used to solve the system . Secondly ,the convergence of the tracking‐differentiator is obtained by Riemann lemma .Finally ,some numerical simulations demonstrate that the proposed tracking‐differentiator can extract differential sig‐nal effectively .
