DJEMAI Mohamed

Dr. Mohamed Djemai is a Full Professor at École Nationale Supérieure de l'Électronique et de ses Applications (ENSEA), Cergy, and INSA Hauts-de-France. He is affiliated with the Quartz Laboratory (EA 7393) and LAMIH UMR CNRS 8201 at University Polytechnic Hauts-de-France. His research focuses on nonlinear control systems theory, with emphasis on hybrid and variable structure systems, sliding mode approaches, fault detection, and applications to power systems, robotics, and vehicle dynamics.

• IEEE Senior Member
• Associate Editor for Nonlinear Analysis: Hybrid Systems
• Co-Facilitator of National Working Group GT-SDH (2014–present)
• Member of IFAC-TC-1.3 (Discrete Event and Hybrid Systems) since 2001
• Member of IFAC-TC-2.1 (Control Design) since 2005

His recent publications address fractional-order control of multiagent systems, stability analysis on time scales, fault-tolerant satellite attitude control, and robust consensus algorithms for nonlinear systems. Key methodologies include sliding mode control, event-triggered control, and observer-based fault detection. Current teaching activities encompass diagnostics, linear systems, signal processing, and sensor conditioning.

The trend in Dr. Djemai's research since 2022 involves advanced control strategies for cyber-physical systems, distributed fault detection mechanisms, and time scale theory applications to intermittent communication problems. Notable collaborations include work with Michael Defoort, Stefano Di Gennaro, and international institutions like Kyungpook National University and University of Reims.

Scientific contributions include:

• IEEE Senior Member recognition
• Development of robust exact filtering differentiators
• Innovations in fixed-time consensus protocols
• Leadership in IFAC technical committees
• Editorial role in hybrid systems analysis

His laboratory work at Quartz and LAMIH supports applications in aerospace systems, renewable energy conversion, and industrial risk management architectures.
