Abstract
In this paper, some kinds of linear and nonlinear tracking-differentiators are designed by using suitable exponent functions instead of switch functions, and the stability of these tracking-differentiators is proved. From the result of simulations, it is manifest that the tracking speeds of these kinds of linear and nonlinear tracking-differentiators are very high, and their design procedures are simple.
