He has edited a book for Springer entitled "Applications of sliding mode control", in 2017.Jawhar Ghommam is a Professor in Control Theory and Robotics at the National Institute of Applied Science and Technology, University of Carthage, Tunis. In Jannuary 2018 he joined the Departement of Electrical and Computer Engineering at the College of Engineering of the Sultan Quaboos University in Oman. He's got the BSc degree in Computer and Control Engineering from the National Institute and Applied Sciences and Technology (INSAT) in 2003 in Tunis. He's got the DEA ( MSc) degree form the university of Montpelier at the Laboratoire d'Informatique, Robotique et Micro-électronique (LIRMM, France) in 2004 and later on in 2008 a Ph.D in Control Engineering degree jointly from the National Engineering School of Sfax and the university of Orleans in France. From September 2008 through September 2010 he had the privilege of regularly visiting a distinguished university at the Balearic Islands (Spain), where he served as a research contributor and Senior lecturer on cooperative control algorithms and a lecturer on time delayed systems. He also has the privilege of visiting the GREPCI research group on the basis of two months yearly since 2010. J. Ghommam occupies a permanent research position at the Control Energy Management Laboratory (CEM-Lab) at Sfax-Tunisia. His Research interests include fundamental motion control concepts for nonholonomic/underactuated vehicle systems, nonlinear and adaptive control; intelligent and autonomous control of networked unmanned systems, team cooperation, consensus achievement,and sensor networks. He is the author/coauthor of about 57 technical papers in international journals, andrefereed conferences. He serves as a regular referee for many international journals in the led of Control and Robotics.Quanmin Zhu is Professor in control systems at Department of Engineering Design and Mathematics, University of the West of England, Bristol, UK. He obtained his MSc. in Harbin Institute of Technology, China in 1983 and PhD in Faculty of Engineering, University of Warwick, UK in 1989. His main research interest is in the area of nonlinear system modelling, identification, and control. He has published over 160 papers on these topics and provided consultancy to various industries.
