Brief History
Dr. Khayati obtained his Engineering degree in Electro-Mechanics from the École Nationale de l'Industrie Minérale (ÉNIM) in Rabat, Morocco, in 1995. He went on to obtain the DESA (master) degree in Industrial Process Control from the École Mohammadia d'Ingénieurs (ÉMI) in Rabat, Morocco in 1998. He earned his Engineering Ph.D. degree in Control and Robotics from the École de Technologie Supérieure (ÉTS) in Montreal, Canada, in 2006. In 2007, he was a research associate in the Control and Robotics (CoRo) lab at the ÉTS.
Dr. Khayati is currently an Associate Professor at RMCC where he has been since August 13, 2007. Before coming to RMCC, he worked as a part-time lecturer and a teaching assistant at ÉTS between 2001 and 2007. From 1999 to 2000, he worked as a part-time assistant professor at the Université Libre de Tunis (ULT) in Tunisia. He was a full-time assistant professor from 1998 to 2000 at the Institut Préparatoire aux Études d'Ingénieurs de Tunis (IPÉIT) in Tunisia. Dr. Khayati's research interests include aspects of control systems: linear and nonlinear control, robust control and nonlinear adaptive observers using linear matrix inequality (LMI) framework. He focuses particularly on control of electromechanical plants, robot arms and pneumatic actuators involving friction behaviour. He works on the positioning tracking and dynamic friction compensation techniques based on the LuGre the generalized Maxwell-slip (GMS) models. He is working now on new methods of nonlinear control for nonlinear perturbed and/or uncertain dynamics. These methods comprise: 1) nonlinear control based on Kronecker product and vector power series, and 2) adaptive sliding mode control techniques.
