英文摘要

      This paper proposes an extensive analysis of the nonlinear tracking-differentiator on the working process and pa-rameters 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 ageeable performance and owns a flexible, uncouple turung technique. This amelioration renders this unit more applicable to practice than ever.
