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 ...

Laboratory Tests to Assess Optimal Agricultural Residue Traits for an Abrasive Weed Control System
(2016)
One of the biggest challenges to organic agricultural production and herbicide resistant crops in industrialized countries today is the non-chemical control of weed plants. Studies of new tools and methods for weed control ...

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 ...

Analysis of aircraft trajectory uncertainty using Ensemble Weather Forecasts
(The European Conference for AeroSpace Sciences (EUCASS), 2017)
The problem of aircraft trajectory prediction subject to weather uncertainty is addressed. In particular, a probabilistic analysis of aircraft fuel consumption taking into account wind uncertainty is presented. The wind ...

Optimal control of cruise flight at constant altitude
(International Council of the Aeronautical Sciences (ICAS), 2010-09-19)
Cruise optimization at constant altitude is formulated as a singular optimal control problem. The cases of maximum range, minimum direct operating cost and minimum fuel with fixed arrival time are analyzed, providing a ...

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. ...
