A Weak Notion of Symmetry for Control Systems
Jake Welde, Riley Link, Pieter van Goor
Symmetry (or invariance) is a powerful structural property that enables efficient, effective solutions for estimation and control. However, the constraints imposed on a system's dy…
Equivariant Filter Design for Acoustic and Depth Aided Inertial Navigation Systems
Arihant Lunawat, Pieter van Goor, Frank Dellaert +1
Autonomous Underwater Vehicles (AUVs) navigating without GPS typically fuse inertial measurements with acoustic Doppler Velocity Log (DVL) velocities and pressure-derived depth. Po…
The Iterative Equivariant Filter
Pieter van Goor, James Richard Forbes
This paper presents the iterative equivariant filter (IterEqF). The iterative extended Kalman filter (IterEKF) replaces the standard EKF correction step with an iterative correctio…
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…
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…
