An implicit discrete-time version of the twisting sliding-mode control algorithm is considered. The framework of variational inequalities is used to define the control input values. This provides the foundation for both the analysis of the controller and the numerical computations. The controller is shown to be well-defined and the discrete-time cl...
This paper proposes a new ellipsoid-based guaranteed state estimation approach for linear discrete-time systems with bounded perturbations and bounded measurement noise. This approach is based on the minimization of the radius of the ellipsoidal state estimation set. Firstly, the ellipsoidal state estimation is computed by o -line solving a Linear ...
One of the most challenging problems in AC drives applications is the design of a simple plug-in adaptation scheme to estimate the unknown rotor resistance and load torque for the industry-standard indirect field oriented control. In this paper we give the first globally convergent solution to this problem for torque control of current-fed inductio...
Two goals are sought in this paper: namely, to provide a succinct overview on algebraic techniques for numerical differentiation and parameter estimation for linear systems and to present novel algebraic methods in the case of several variables. The state-of-art in the introduction is followed by a brief description of the methodology in the subseq...
Ce papier a pour but l’étude de la stabilité asymptotique des systèmes différentiels linéaires à retards commensurables de type retardé. Dans l’approche fréquentielle, il est bien connu que la stabilité asymptotique d’un tel système est assurée par la condition que les racines du quasipolynôme correspondant ont des parties réelles négatives. Une ap...
The present paper is an accessible digest, along with extensions, of previous work by the authors. We propose an unifying and versatile framework for a class of discrete time systems whose state is an element of a group, that we call linear observation systems on groups. Those systems strictly mimic linear systems in the sense that + is replaced wi...
The access to electricity for isolated communities is capital for improving life in thosesocieties. The use of renewable energy sources (renewables) and energy storage systems is the keyfor clean energy supply in remote areas without the main grid. The standalone operation of renewablesrepresents a challenge for operation and reliability, therefore...

Vehicle rollover is a very serious problem when considering the safety of heavy vehicles, which can result in large financial and environmental consequences. This paper investigates the interest of a Linear Parameter Varying (LPV) controller for an active anti-roll bar system of single unit heavy vehicles, in order to enhance roll stability. We pro...
