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…
Super-twisting over networks: A Lyapunov approach for distributed differentiation
Rodrigo Aldana-López, Irene Perez Salesa, David Gomez Gutierrez +2
We study distributed differentiation, where agents in a networked system estimate the average of local time-varying signals and their derivatives under mild assumptions on the agen…
Hierarchical parameter estimation for distributed networked systems: a dynamic consensus approach
Ariana R. Mendez-Castillo, Rodrigo Aldana-Lopez, Antonio Ramirez-Trevino +2
This work introduces a novel two-stage distributed framework to globally estimate constant parameters in a networked system, separating shared information from local estimation. Th…
Exact Leader Estimation: A New Approach for Distributed Differentiation
Rodrigo Aldana-Lopez, David Gomez-Gutierrez, Elio Usai +1
A novel strategy aimed at cooperatively differentiating a signal among multiple interacting agents is introduced, where none of the agents needs to know which agent is the leader,…
Optimal robust exact first-order differentiators with Lipschitz continuous output
Rodrigo Aldana-Lopez, Richard Seeber, Hernan Haimovich +1
The signal differentiation problem involves the development of algorithms that allow to recover a signal's derivatives from noisy measurements. This paper develops a first-order di…
Implementing prescribed-time convergent control: sampling and robustness
Hernan Haimovich, Rodrigo Aldana-Lopez, Richard Seeber +1
According to recent results, convergence in a prespecified or prescribed finite time can be achieved under extreme model uncertainty if control is applied continuously over time. T…
