Differentiator for Noisy Sampled Signals with Best Worst-Case Accuracy
Hernan Haimovich, Richard Seeber, Rodrigo Aldana-López +1
This paper proposes a differentiator for sampled signals with bounded noise and bounded second derivative. It is based on a linear program derived from the available sample informa…
Designing predefined-time differentiators with bounded time-varying gains
Rodrigo Aldana-López, Richard Seeber, David Gómez-Gutiérrez +2
There is an increasing interest in designing differentiators, which converge exactly before a prespecified time regardless of the initial conditions, i.e., which are fixed-time con…
An arbitrary-order predefined-time exact differentiator for signals with exponential growth bound
David Gómez-Gutiérrez, Rodrigo Aldana-López, Richard Seeber +2
There is a growing interest in differentiation algorithms that converge in fixed time with a predefined Upper Bound on the Settling Time (UBST). However, existing differentiation a…
