LMI-based 2-DoF control design of a manipulator via T-S descriptor approach

van Anh Nguyen Thi, Tran Anh-Tu Nguyen, Antoine Dequidt, Laurent Vermeiren, Michel Dambrine

This paper presents a method for the control design of a manipulator. The design goal is to achieve a guaranteed H∞ model reference tracking performance with respect to bounded reference inputs through a 2-DoF control scheme. To achieve this goal, the manipulator system is represented by a Takagi-…

LMI-Based Controller Design for Time-Delay Nonlinear Descriptor Systems with Guaranteed Exponential Estimates

Juan Carlos Arceo Luzanilla, Raúl Villafuerte, Víctor Estrada Manzo, Miguel Bernal

This report is concerned with stability and stabilization of time-delay nonlinear nonsigular descriptor systems. Based-on a Lyapunov-Krasovskii functional and an exact convex representation of the system, conditions in the form of linear matrix inequalities are found that guarantee exponential…

Local stabilization of discrete-time TS descriptor systems

Zsofia Lendek, Gábor Nagy, Jimmy Lauber

Descriptor models are naturally obtained from the Euler–Lagrange modeling approach to mechanical systems. Since the underlying system is nonlinear, global stabilization and/or tracking is possible only in a limited number of cases. Therefore, we develop conditions for local stabilization and…

Consensus of Double-Integrator Multi-Agent Systems Using Decentralized Model Predictive Control

Pipit Anggraeni, Michael Defoort, Mohamed Djemai, Aries Subiantoro, Abdul Muis

This paper studies the consensus for a group of agents which have a discrete-time double-integrator dynamics. To solve this problem, a Model Predictive Control (MPC) scheme is introduced. The proposed control protocol is decentralized and is designed by combining graph theory with a predictive…

Fixed-Time Tracking Control of Chained-form Nonholonomic System with External Disturbances

Pipit Anggraeni, Michael Defoort, Mohamed Djemai, Zongyu Zuo

This paper studies the fixed-time tracking problem for chained-form nonholonomic systems under matched external disturbances. The proposed method is to construct a tracking controller such that the tracking errors converge to zero for any arbitrary initial tracking error at fixed-time. First of all…

Wetting and evaporation of nanosuspension droplets, Mouillage et évaporation de gouttelettes de nanosuspensions

Maryam Maria Parsa

Evaporation of liquid droplets containing non-volatile solutes is an omnipresent phenomenon in daily life, e.g., coffee stains on solid surfaces. The study of pattern formation of the particles left after the evaporation of a sessile droplet has attracted the attention of many researchers during…, L’évaporation de gouttes de liquides contenant des particules non volatiles représente un phénomène largement présent dans la vie quotidienne, à l’image des traces laissées par le marc de café après séchage. L’étude de la morphologie des dépôts de particules présente un grand intérêt dans les…

Active Side Shafts Torsion Damping Control for Hybrid Electric Vehicles

Walter Lhomme, Florian Tournez, Sebastien Delprat, Sebastien Paganelli

Hybrid electric vehicles generally use an internal combustion engine and one or several electric drives. Optimization-based energy management strategies computes a power split between both the engine and the machine to minimize the fuel consumption. Nevertheless, the driving comfort is not taken…
