Business Jet Large-Scale Model Approximation and Vibration Control

Autor: Charles Poussot-Vassal, Jean-Patrick Lacoste, Thomas Loquen, Pierre Vuillemin, Olivier Cantinaud

Publikováno v: ALCOSP

In this paper, a procedure allowing to design an H∞-based low order anti-vibration controller is proposed. The contributions of the paper lie in the first specification and application of recent (i) model approximation and (ii) H∞ structured cont

Autor: Jose Alvaro Perez, Christelle Pittet, Christelle Cumer, Thomas Loquen, Daniel Alazard

Publikováno v: Journal of Dynamic Systems, Measurement, and Control
Journal of Dynamic Systems, Measurement, and Control, American Society of Mechanical Engineers, 2016, 138 (12), 16 p. ⟨10.1115/1.4034149⟩

The main objective of this study is to propose a methodology to build a parametric linear model of Flexible Multibody Systems for control design. This approach uses a combined Finite Element - State Space Approach based on component modes synthesis a

Piecewise quadratic Lyapunov functions for linear control systems with First Order Reset Elements

Autor: Dragan Nesic, Thomas Loquen, Andrew R. Teel, Sophie Tarbouriech, Christophe Prieur, Luca Zaccarian

Publikováno v: IFAC Proceedings Volumes. 43:807-812

For a class of reset control systems, we reconsider the piecewise quadratic Lyapunov function construction proposed in Zaccarian et al. [2005]. In particular, we propose an alternative construction that addresses an analysis subtlety overlooked in th

Analyse de stabilité des systèmes avec réinitialisation en présence d'incertitudes

Autor: Sophie Tarbouriech, Thomas Loquen, Christophe Prieur

Publikováno v: Journal Européen des Systèmes Automatisés. 41:941-960

This paper is dedicated to the study of specific hybrid systems: reset control systems. A reset system is a system whose states are reset whenever its output and input satisfy an appropriate relationship. Stability analysis and L2-performance are stu

Two-input two-output port model for mechanical systems

Autor: Thomas Loquen, Daniel Alazard, José Alvaro Perez Gonzalez, Christelle Cumer

Publikováno v: AIAA Guidance, Navigation, and Control Conference.

This paper proposes a double input output port transfer to model complex mechanical systems composed of several sub-systems. The sub-structure decomposition is revisited from the control designer point of view. The objective is to develop modelling t
