Mixed Regular and Impulsive Sampled-data LQR
Jamal Daafouz, Jérôme Lohéac, Romain Postoyan
We investigate the benefits of combining regular and impulsive inputs for the control of sampled-data linear time-invariant systems. We first observe that adding an impulsive term…
Discrete-Time Conewise Linear Systems with Finitely Many Switches
Jamal Daafouz, Jérôme Lohéac, Constantin Morărescu +1
We investigate discrete-time conewise linear systems (CLS) for which all the solutions exhibit a finite number of switches. By switches, we mean transitions of a solution from one…
A TBLMI Framework for Harmonic Robust Control
Flora Vernerey, Pierre Riedinger, Jamal Daafouz
The primary objective of this paper is to demonstrate that problems related to stability and robust control in the harmonic context can be effectively addressed by formulating them…
A harmonic framework for the identification of linear time-periodic systems
Flora Vernerey, Pierre Riedinger, Andrea Iannelli +1
This paper presents a novel approach for the identification of linear time-periodic (LTP) systems in continuous time. This method is based on harmonic modeling and consists in conv…
On solving infinite-dimensional Toeplitz Block LMIs
Flora Vernerey, Pierre Riedinger, Jamal Daafouz
This paper focuses on the resolution of infinite-dimensional Toeplitz Block LMIs, which are frequently encountered in the context of stability analysis and control design problems…
Stability analysis of optimal control problems with time-dependent costs
Sifeddine Benahmed, Romain Postoyan, Mathieu Granzotto +3
We present stability conditions for deterministic time-varying nonlinear discrete-time systems whose inputs aim to minimize an infinite-horizon time-dependent cost. Global asymptot…
Solving Infinite-Dimensional Harmonic Lyapunov and Riccati equations
Pierre Riedinger, Jamal Daafouz
In this paper, we address the problem of solving infinite-dimensional harmonic algebraic Lyapunov and Riccati equations up to an arbitrary small error. This question is of major pr…
Harmonic Pole Placement
Pierre Riedinger, Jamal Daafouz
In this paper, we propose a method to design state feedback harmonic control laws that assign the closed loop poles of a linear harmonic model to some desired locations. The proced…
Necessary and Sufficient Conditions for Harmonic Control in Continuous Time
Nicolas Blin, Pierre Riedinger, Jamal Daafouzi +2
In this paper, we revisit the concepts and tools of harmonic analysis and control and provide a rigorous mathematical answer to the following question: when does an harmonic contro…
Stability analysis of a general class of singularly perturbed linear hybrid systems
Jihene Ben Rejeb, Irinel-Constantin Morărescu, Antoine Girard +1
Motivated by a real problem in steel production, we introduce and analyze a general class of singularly perturbed linear hybrid systems with both switches and impulses, in which th…
Co-design of output feedback laws and event-triggering conditions for linear systems
Mahmoud Abdelrahim, Romain Postoyan, Jamal Daafouz +1
We present a procedure to simultaneously design the output feedback law and the event-triggering condition to stabilize linear systems. The closed-loop system is shown to satisfy a…
Stabilization of nonlinear systems using event-triggered output feedback controllers
Mahmoud Abdelrahim, Romain Postoyan, Jamal Daafouz +1
The objective is to design output feedback event-triggered controllers to stabilize a class of nonlinear systems. One of the main difficulties of the problem is to ensure the exist…
Event-triggered control of nonlinear singularly perturbed systems based only on the slow dynamics
Mahmoud Abdelrahim, Romain Postoyan, Jamal Daafouz
Controllers are often designed based on a reduced or simplified model of the plant dynamics. In this context, we investigate whether it is possible to synthesize a stabilizing even…
