Dong, Cunhui; Lian, Xing; Wu, Xiaohui A research on a linear tracking-differentiator to track interference signal. (Chinese. English summary) Zbl 1340.93081 Basic Sci. J. Text. Univ. 27, No. 4, 439-442, 458 (2014). Summary: 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 the Riemann lemma. Finally, some numerical simulations demonstrate that the proposed tracking-differentiator can extract differential signal effectively.
