Abstract :
A finite-time-convergent non-homogeneous robust exact differentiator is constructed, which provides for faster convergence compared with the standard homogeneous differentiator. The optimal asymptotic features of the standard differentiator are preserved. Computer simulation confirms the theoretical results.
