Autonomous and non-autonomous fixed-time leader-follower consensus for second-order multi-agent systems
Miguel A. Trujillo, Rodrigo Aldana-López, David Gomez Gutierrez +3
This paper addresses the problem of consensus tracking with fixed-time convergence, for leader-follower multi-agent systems with double-integrator dynamics, where only a subset of…
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…
On the Efficient Implementation of an Implicit Discrete-Time Differentiator
José Eduardo Carvajal-Rubio, Juan Diego Sánchez-Torres, Michael Defoort +2
New methodologies are designed to reduce the time complexity of an implicit discrete-time differentiator and the simulation time to implement it. They rely on Horner's method and t…
A Discrete-Time Matching Filtering Differentiator
J. E. Carvajal-Rubio, J. D. Sánchez-Torres, M. Defoort +2
This paper presents a time discretization of the robust exact filtering differentiator, a sliding mode differentiator coupled to filter, which provides a suitable approximation to…
Leader-following consensus for multi-agent systems with nonlinear dynamics subject to additive bounded disturbances and asynchronously sampled outputs (long version)
Tomas Menard, Ali Syed, Emmanuel Moulay +2
This paper is concerned with the leader-following consensus problem for a class of Lipschitz nonlinear multi-agent systems with uncertain dynamics, where each agent only transmits…
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…
