| Abstract: | An improved tracking differentiator(ITD) is proposed based on the study of typical tracking differentiators (TD). Integrating the merits of linear TD and nonlinear TD together, ITD not only has no chattering phenomenon, but also has excellent dynamic responses and strong filtering performance. Both tracking and differentiation can be realized conveniently for any signals by using ITD. It has simple form and is easy to implement in engineering. Simulation results show that the algorithm presented has excelle... |
