Distributed ToA Localization of Acoustic Sources with Unknown Time of Emission via Operator Splitting
Anton Tolstonogov, David Cabecinhas, Pedro Batista +1
Localization of non-cooperative acoustic sources using multiple spatially distributed receivers is critical for applications such as marine-life tracking, search-and-rescue operati…
Moving Horizon Estimation for Underwater Target Tracking Based on Time-Difference-of-Arrival Measurements
Anton Tolstonogov, David Cabecinhas, Pedro Batista +1
There has been a flurry of activity in the development of robotic systems to localize and track underwater man-made or natural targets based on sparse acoustic data. Compelling exa…
Orbital Station-Keeping in the Earth-Moon System via Nonlinear Backstepping
António Nunes, Pedro Batista, Sérgio Brás
A nonlinear orbital station-keeping solution for the circular and elliptic versions of the Earth-Moon Restricted Three-Body Problem (R3BP) is developed via a backstepping technique…
A Floquet Mode LQR for Orbital Station-Keeping in Cislunar Space
António Nunes, Sérgio Brás, Pedro Batista
A linear optimal control law for orbital station-keeping in the Earth-Moon Restricted Three Body Problem (R3BP) is developed via Linear Quadratic Regulator (LQR) theory. First, the…
Nonlinear backstepping with saturation for low-thrust station-keeping of libration point orbits
António Nunes, Sérgio Brás, Pedro Batista
This paper presents a novel nonlinear backstepping control law for continuous, low-thrust station-keeping in the Earth-Moon system. Quasi-periodic libration point orbits are target…
Designing trajectories in the Earth--Moon system: a Levenberg--Marquardt approach
António Nunes, Sérgio Brás, Pedro Batista +1
Trajectory design in cislunar space under a high-fidelity ephemeris model (HFEM) is pursued through a nonlinear optimization perspective anchored on the transition of solutions fro…
Distributed decentralized receding horizon control for very large-scale networks with application to satellite mega-constellations
Leonardo Pedroso, Pedro Batista
The implementation feasibility of control algorithms over very large-scale networks calls for hard constraints regarding communication, computational, and memory requirements. In t…
Position USBL/DVL Sensor-based Navigation Filter in the presence of Unknown Ocean Currents
M. Morgado, P. Batista, P. Oliveira +1
This paper presents a novel approach to the design of globally asymptotically stable (GAS) position filters for Autonomous Underwater Vehicles (AUVs) based directly on the nonlinea…
A Sensor-based Long Baseline Position and Velocity Navigation Filter for Underwater Vehicles
Pedro Batista, Carlos Silvestre, Paulo Oliveira
This paper presents a novel Long Baseline (LBL) position and velocity navigation filter for underwater vehicles based directly on the sensor measurements. The solution departs from…
