Abstract :
Homogeneous Sliding Mode (HSM) differentiators provide for the high-accuracy robust finite-time-exact estimation of derivatives. It is shown that their digital implementation misses the homogeneity, and respectively features much worse accuracy. A novel HSM differentiator is proposed, improving the accuracy of its digital one-Euler-step implementation.
