Bilateral boundary control of one-dimensional first- and second-order PDEs using infinite-dimensional backstepping
(Institute of Electrical and Electronics Engineers (IEEE), 2016)
This paper develops an extension of infinite-dimensional backstepping method for parabolic and hyperbolic systems in one spatial dimension with two actuators. Typically, PDE backstepping is applied in 1-D domains with an ...

Output-feedback control of the longitudinal flight dynamics using adaptative backstepping
(Institute of Electrical and Electronics Engineers (IEEE), 2011)
An adaptive backstepping approach is used to design an output feedback control law for the longitudinal dynamics of an Unmanned Air Vehicle (UAV). The resulting nonlinear controller makes the system to follow references ...

A Flatness-Based Trajectory Planning Algorithm for Rendezvous of Single-Thruster Spacecraft
(Elsevier, 2018)
This work presents a trajectory planning algorithm for spacecraft rendezvous with a passive target. The main assumption is that the chaser vehicle has a single thruster and an attitude control system (e.g. reaction wheels) ...

A Predictive Guidance Algorithm for Autonomous Asteroid Soft Landing
(Elsevier, 2018)
The objective of this work is to present a closed-loop guidance algorithm for landing a probe on an irregular shaped rotating asteroid. The main assumption is that the spacecraft is orbiting close to the asteroid and has ...

Trajectory Planning for Spacecraft Rendezvous with On / Off Thrusters
(Elsevier, 2011)
The objective of this work is to present a trajectory planning algorithm for spacecraft rendezvous that is able to incorporate Pulse-Width Modulated (PWM) control signals. The algorithm is based on linearization around a ...

Output feedback control of radially-dependent reaction-diffusion PDEs on balls of arbitrary dimensions
(Elsevier, 2020)
Recently, the problem of boundary stabilization and estimation for unstable linear constant-coefficient reaction-diffusion equation on n-balls (in particular, disks and spheres) has been solved by means of the backstepping ...

Volterra boundary control laws for a class of nonlinear parabolic partial differential equations
(Elsevier, 2004)
The efforts on boundary control of general classes of nonlinear parabolic PDEs with nonlinearities of superlinear growth have so far only resulted in counterexamples-results that show that finite time blow up occurs for ...

Optimal Trajectory Generation for UAVs Using Dynamic Trajectory Modeling
(Proceedings of the 1st Workshop on Research, Development and Education on Unmanned Aerial Systems (RED-UAS 2011), 2011-11-30)
The generation of optimal trajectories for UAVs in the presence of an average horizontal wind is studied. The generation is performed off line (strategic planning). The approach is based on the discretization of the ...

A Symmetry-Based Unscented Particle Filter for State Estimation of a Ballistic Vehicle
(Elsevier, 2023)
The problem of state estimation for vehicles when an initial fix is highly uncertain and/or the number of sensors is not sufficient (and changes with time) is very relevant for both aircraft and spacecraft navigation. This ...
