Tracking Control for a Dynamic Model of an Underwater Submersible
Matthew Hampsey, Pieter van Goor, Ravi Banavar +1
Underwater vehicles are naturally modelled as rigid bodies on SE(3) subjected to added mass effects. The passivity of the Hamiltonian structure of the system can be exploited to de…
Equivariant Observer Design on SL(3) for Image Intensity-Based Homography Estimation
Tarek Bouazza, Pieter van Goor, Robert Mahony +1
This paper addresses the problem of homography estimation using a nonlinear observer designed on the Lie group that exploits the full image information through dir…
A Comparative Study of INDI and NDI with Nonlinear Disturbance Observer for Aerial Robotics
Benedetta Rota, Mirko Mizzoni, Amr Afifi +2
This work presents a simulation-based comparative robustness analysis of Incremental Nonlinear Dynamic Inversion (INDI) and Nonlinear Dynamic Inversion augmented with a nonlinear d…
Synchronous Observer Design for Landmark-Inertial SLAM with Magnetometer and Intermittent GNSS Measurements
Arkadeep Saha, Pieter van Goor, Ravi Banavar
In Landmark-Inertial Simultaneous Localisation and Mapping (LI-SLAM), the positions of landmarks in the environment and the robot's pose relative to these landmarks are estimated u…
A Weak Notion of Symmetry for Dynamical Systems
Jake Welde, Pieter van Goor
Many nonlinear dynamical systems exhibit symmetry, affording substantial benefits for control design, observer architecture, and data-driven control. While the classical notion of…
The Geometry of Coordinated Trajectories for Non-stop Flying Carriers Holding a Cable-Suspended Load
Pieter van Goor, Chiara Gabellieri, Antonio Franchi
This work considers the problem of using multiple aerial carriers to hold a cable-suspended load while remaining in periodic motion at all times. Using a novel differential geometr…
