A preliminary study on integrating operation flexibility within semi-heterarchical FMS control

Nawal Ghazi, Gabriel Zambrano Rey, Abdelghani Bekrar, Damien Trentesaux, Mohamed Tadjine

This study aims to analyze the integration of operation flexibility (OF) within a semi-heterarchical flexible manufacturing system (SHFMS) control architecture. This architecture is composed of two types of decisional entities, global and local, and it exists three different modes in which those…

A Variable Neighborhood Search (VNS) metaheuristic for Multiprocessor Scheduling Problem with Communication Delays

Abdessamad Ait El Cadi, Rabie Ben Atitallah, Nenad Mladenovic, Abdelhakim Artiba

The purpose of this paper is to present a Variable Neighborhood Search (VNS) metaheuristic for solving the Multiprocessor Scheduling Problem with Communication Delays (MSPCD). The MSPCD problem considers scheduling task graph on a multiprocessor system, taking into account communication delays. The…

Early detection of abnormal patient arrivals at hospital emergency department

Fouzi Harrou, Ying Sun, Farid Kadri, Sondès Chaabane, Christian Tahon

Overcrowding is one of the most crucial issues confronting emergency departments (EDs) throughout the world. Efficient management of patient flows for ED services has become an urgent issue for most hospital administrations. Handling and detection of abnormal situations is a key challenge in EDs.…

Multicellular Converter: A Benchmark for Control and Observation for Hybrid Dynamical Systems

Michael Defoort, Jérémy van Gorp, Mohamed Djemai

Due to their cost and their reliability, multicellular converters are interesting devices to supply electrical systems in many applicative fields. The first part of this chapter deals with the controller design for switching power converters, which are a particular class of switched systems. Two…

Observer Design for Discrete-Time Switching Nonlinear Models

Zsofia Lendek, Paula Raica, Jimmy Lauber, Thierry-Marie Guerra

Switched systems are often described by continuous and discrete dynamics as well as their interactions. Although results are available for linear switching systems, for nonlinear switching models few results exist. In this chapter, we consider observer design for discrete-time switching nonlinear…

On the Observation Analysis and Observer Design for a Class of Hybrid Continuous-Discrete Dynamic System

Noureddine Manamanni, Mohamed Djemai, Jean-Pierre Barbot

This chapter deals with observability conditions and state observer design for a class of hybrid systems whose the continuous part combines continuous and discrete dynamics. The main contribution of the work lies in the performed observability conditions for this class of systems and the design of…

An adaptive modified super-twisting sliding mode controller: Applied to the active suspension system

Jagat Jyoti Rath, Suneel Kumar Kommuri, Kalyana Chakravarthy Veluvolu, Michael Defoort, Sivanagaraja Tatinati

A robust higher order sliding mode algorithm combining the merits of the modified super-twisting algorithm and the adaptive super-twisting algorithm has been proposed for a class of nonlinear uncertain systems in this article. For a class of linearly growing perturbations whose upper bounds are not…

Performance comparison of sliding mode observers for back EMFs based speed estimation in PMSM

Suneel Kumar Kommuri, Jagat Jyoti Rath, Kalyana Chakravarthy Veluvolu, Michael Defoort, Sivanagaraja Tatinati

This paper proposes a second-order high-speed sliding mode (SHSM) observer and compares the performance with the recent higher-order sliding mode (HOSM) observer for the problem of sensorless speed estimation in the permanent magnet synchronous motor (PMSM). In which, a sigmoid function is…
