Tracking Differentiator in the Application of Signal Processing and Theory Research

In this paper, we bring out the theory study result of tracking differentiator and example for signal processing. Tracking differentiator has the quality that does not rely on the presumed state equations when tracking projects, for further application nonlinear tracking differentiator is developed here. And with an example, we prove that the nonlinear tracking differentiator can track the project effectively and the related theory for the solution is also given.
