Analysis and Improvement of the Nonlinear Tracking Differentiator

本文对非线性跟踪微分器的工作机理和参数意义进行了深入分析，发现了超调产生的根源及参数相互制约的原因，通过对其开关平面函数的改进，改善了信号的品质，得到了灵活解耦的参数整定方法。

This paper proposes an extensive analysis of the nonlinear tracking differentiator on the working process and parameters tuning, based on which the source of the overshoot and the cause that coupling to tune are cleared. Thus, an improved switching function is put forward to the developed nonlinear tracking differentiator, which exhibits an agreeable performance and owns a flexible, uncouple tuning technique. This amelioration renders this unit more applicable to practice than ever.
