Safety-Critical Control for Quadrotor UAVs via Decentralized Navigation Functions
Omayra Yago Nieto, Alexandre Anahory Simoes, Leonardo Colombo
We study safety-critical control for teams of quadrotor UAVs driven by decentralized navigation functions under learned model uncertainty. These functions generate fully actuated t…
Robust Geometric Control of Catenary Robots under Unstructured Force Uncertainties
Alexandre Anahory Simoes, Leonardo Colombo
This paper considers the robust control of a catenary robot composed of two quadrotors connected by an inextensible cable. The system is modeled on \(SE(3)\), with the cable treate…
Stable Walking for Bipedal Locomotion under Foot-Slip via Virtual Nonholonomic Constraints
Leonardo Colombo, Álvaro Rodríguez Abella, Alexandre Anahory Simoes +1
Foot slip is a major source of instability in bipedal locomotion on low-friction or uncertain terrain. Standard control approaches typically assume no-slip contact and therefore de…
Virtual Constraint for a Quadrotor UAV Enforcing a Body-Axis Pointing Direction
Alexandre Anahory Simoes, Leonardo Colombo, Juan Giribet +1
We propose a geometric control framework on for quadrotors that enforces pointing-driven missions without completing a full attitude reference. The mission is encoded throu…
Dual-quaternion learning control for autonomous vehicle trajectory tracking with safety guarantees
Omayra Yago Nieto, Alexandre Anahory Simoes, Juan I. Giribet +1
We propose a learning-based trajectory tracking controller for autonomous robotic platforms whose motion can be described kinematically on . The controller is formu…
Learning-based decentralized control with collision avoidance for multi-agent systems
Omayra Yago Nieto, Alexandre Anahory Simoes, Juan I. Giribet +1
In this paper, we present a learning-based tracking controller based on Gaussian processes (GP) for collision avoidance of multi-agent systems where the agents evolve in the specia…
Virtual nonlinear nonholonomic constraints from a symplectic point of view
Efstratios Stratoglou, Alexandre Anahory Simoes, Anthony Bloch +1
In this paper, we provide a geometric characterization of virtual nonlinear nonholonomic constraints from a symplectic perspective. Under a transversality assumption, there is a un…
Retraction maps in optimal control of nonholonomic systems
Alexandre Anahory Simoes, María Barbero Liñán, Anthony Bloch +2
In this paper, we compare the performance of different numerical schemes in approximating Pontryagin's Maximum Principle's necessary conditions for the optimal control of nonholono…
Geometric Stabilization of Virtual Nonlinear Nonholonomic Constraints
Efstratios Stratoglou, Alexandre Anahory Simoes, Anthony Bloch +1
In this paper, we address the problem of stabilizing a system around a desired manifold determined by virtual nonlinear nonholonomic constraints. Virtual constraints are relationsh…
Nonholonomic mechanics and virtual constraints on Riemannian homogeneous spaces
Efstratios Stratoglou, Alexandre Anahory Simoes, Anthony Bloch +1
Nonholonomic systems are, so to speak, mechanical systems with a prescribed restriction on the velocities. A virtual nonholonomic constraint is a controlled invariant distribution…
Geometric stabilization of virtual linear nonholonomic constraints
Alexandre Anahory Simoes, Anthony Bloch, Leonardo Colombo +1
In this paper, we give sufficient conditions for and deduce a control law under which a mechanical control system converges exponentially fast to a virtual linear nonholonomic cons…
Virtual Holonomic and Nonholonomic Constraints on Lie groups
A. Anahory Simoes, A. Bloch, L. Colombo +1
This paper develops a geometric framework for virtual constraints on Lie groups, with emphasis on mechanical systems modeled as affine connection systems. Virtual holonomic and vir…
Reduction by symmetries of contact mechanical systems on Lie groups
Alexandre Anahory Simoes, Leonardo Colombo, Manuel de León +3
We study the dynamics of contact mechanical systems on Lie groups that are invariant under a Lie group action. Analogously to standard mechanical systems on Lie groups, existing sy…
