Assignment of Global Convergence Time Bounds for Exact Differentiators

Description

The tuning of robust exact sliding-mode differentiators is considered, whose convergence time is fixed (i.e., finite and uniformly bounded with respect to the initial condition). A class of first-order differentiators is presented along with a tuning procedure that allows to assign an arbitrary bound for this fixed convergence time. For the uniform robust exact differentiator, which is included as a special case, insights into the tuning and the resulting behavior are shown by means of simulation examples.
