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…
On the design of non-autonomous fixed-time controllers with a predefined upper bound of the settling time
David Gómez-Gutiérrez
This paper aims to introduce a design methodology to stabilize a chain of integrators in a fixed-time with predefined Upper Bound for the Settling-Time (UBST). This approach is bas…
Consistent Discretization of a Class of Predefined-Time Stable Systems
Esteban Jiménez-Rodríguez, Rodrigo Aldana-López, Juan D. Sánchez-Torres +2
As the main contribution, this document provides a consistent discretization of a class of fixed-time stable systems, namely predefined-time stable systems. In the unperturbed case…
A methodology for designing fixed-time stable systems with a predefined upper-bound in their settling time
Rodrigo Aldana-López, David Gómez-Gutiérrez, Marco Tulio Angulo +1
Algorithms having uniform convergence with respect to their initial condition (i.e., with fixed-time stability) are receiving increasing attention for solving control and observer…
