Boundary Feedback Control of Unstable thermoacoustic Oscillations in the Rijke Tube
(Elsevier, 2016)
The problem of boundary stabilization of thermoacoustic oscillations is investigated. The Rijke tube is used as prototype system to study such phenomena. We consider that this system is modelled as a 2 x 2 linear first-order ...

Trajectory tracking for fixed-wing UAV using model predictive control and adaptive backstepping
(Elsevier, 2015)
This paper presents a two layer guidance and control system design for fixed-wing unmanned aerial vehicles (UAV). On the top level, the guidance system makes the airplane follows precomputed references using a novel iterative ...

An Event-Triggered Predictive Controller for Spacecraft Rendezvous Hovering Phases
(Elsevier, 2019)
This work presents an event-triggered model predictive controller for spacecraft hovering phases. The target is assumed to be inert on its an elliptic orbit whereas the chaser has impulsive thrusters. The main goal is to ...

Boundary Control of Coupled Reaction-Advection-Diffusion Systems with Spatially-Varying Coefficients
(Institute of Electrical and Electronics Engineers (IEEE), 2016)
Recently, the problem of boundary stabilization for unstable linear constant-coefficient coupled reaction-diffusion systems was solved by means of the backstepping method. The extension of this result to systems with ...

Backstepping control of a hyperbolic PDE system with zero characteristic speed
(Elsevier, 2022)
In this paper, we study the single-input boundary feedback stabilization of 3 × 3 linear hyperbolic partial differential equations (PDEs) with two counterconvecting PDEs and the third one with zero characteristic speed. ...

Propagation of Initial Mass Uncertainty in Aircraft Cruise Flight
(American Institute of Aeronautics and Astronautics Inc., 2013-03)
The propagation of initial mass uncertainty in cruise flight is studied. Two cruise conditions are analyzed: one with given cruise fuel load and the other with given cruise range. Two different distributions of initial ...

Marcum Q-functions and explicit kernels for stabilization of 2×2 linear hyperbolic systems with constant coefficients
(Elsevier, 2014)
We find the exact analytical solution to a Goursat PDE system governing the kernels of a backstepping-based boundary control law that stabilizes a constant-coefficient 2×2 system of first-order hyperbolic linear PDEs. The ...

Nonlinear bilateral output-feedback control for a class of viscous Hamilton¿Jacobi PDEs
(Elsevier, 2019)
We tackle the boundary control and estimation problems for a class of viscous Hamilton–Jacobi PDEs, considering bilateral actuation and sensing, i.e., at the two boundaries of a 1-D spatial domain. We first solve the ...

Control of the longitudinal flight dynamics of an UAV using adaptive backstepping
(Elsevier, 2011)
An adaptive backstepping approach is used to control the longitudinal dynamics of an Unmanned Air Vehicle (UAV). The nonlinear controller designed makes the system follow references in the aerodynamic velocity and flight ...

Event-based impulsive control for spacecraft rendezvous hovering phases
(AIAA International, 2021)
This work presents an event-triggered controller for spacecraft rendezvous hovering phases. The goal is to maintain the chaser within a bounded region with respect to the target. The main assumption is that the chaser vehicle ...
