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) ...

Kernel well-posedness and computation by power series in backstepping output feedback for radially-dependent reaction–diffusion PDEs on multidimensional balls
(Elsevier, 2023)
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 ...

Pulse-width predictive control for LTV systems with application to spacecraft rendezvous
(Elsevier, 2017)
This work presents a Model Predictive Controller (MPC) that is able to handle Linear Time-Varying (LTV) plants with Pulse-Width Modulated (PWM) control. The MPC is based on a planner that employs a Pulse-Amplitude Modulated ...

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 ...

A flatness-based predictive controller for six-degrees of freedom spacecraft rendezvous
(Elsevier, 2020)
This work presents a closed-loop guidance algorithm for six-degrees of freedom spacecraft rendezvous with a passive target flying in an eccentric orbit. The main assumption is that the chaser vehicle has an attitude control ...

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 ...
