Automatic control & computer engineering


Nizar CHATTI was born in 1985. Since september 2014, he is associate professor in the public engineering school ISTIA (University of Angers) and researcher in LARIS laboratory EA 7315. From January 2014 until July 2014, He was post-doctoral researcher within an industrial project with Airbus (EYCCC Flight Control System TIP Control - FDIR Task (Airbus Operations S.A.S, Toulouse) and the laboratory IMS Bordeaux (ARIA team). This project aimed to propose and to implement model-based diagnosis approaches on the EFCS (Electrical Flight Control System) for detecting faults related to the moving surfaces of the A320 Aircraft. Nizar CHATTI is Ph.D in Automatic control and computer engineering. He received his Engineering degree in Automatics and industrial data processing in 2009, a M.Sc. in Automatic control, computer engineering and Image processing at Ecole Centrale de Lille, France in 2010. He fulfilled his Ph.D degree at the LAGIS laboratory (Polytech-Lille), Villeneuve d’Ascq, France. He was also a member of the European project InTraDE (Intelligent Transportation for Dynamic Environment) and he was working in the WP3A6 which aimed to develop new algorithms for robust supervision and to investigate practical issues in implementing automatic navigation methods in container terminals. His research within the framework of InTraDE concerned diagnosis and supervision of complex systems applied for intelligent transportation and mechatronics Processes by dealing with multi-model approaches namely functional and behavioural ones. He is the author of several papers in this field. He was also teaching Automatic control, Electronics... within the French University IUT in Lille1, France. He worked on modelling and model-based diagnosis of an electrical vehicle and a PEM fuel cell system as applications for his developed algorithms.

  • Sept. 2014-Current: Associate professor in the French public engineering school ISTIA, University of Angers, France. My research activities are carried out within the LARIS Lab EA7315, ISTIA, France.

  • Jan. 2014-July 2014: Post-doctoral Researcher in IMS Lab (Bordeaux, France) within an industrial project with Airbus

I am particularly interested in diagnosis and monitoring problems arising in vehicular technology, robotics and industrial plants, including (but not limited to) the problems of faults detection and isolation and possibilities of reconfiguration as well as supervision of intelligent and autonomous systems to meet the requirements set on efficiency, reliability and safety. My research interests center on developing model-based diagnosis algorithms based on qualitative and quantitative modeling within an integrated approach dedicated for monitoring tasks of dynamic systems. Within this scope, I proposed the Signed Bond Graph (SBG) formalism which extends the use of Bond Graphs to include qualitative reasoning by dealing with its structural and causal features as well as solution methods (Graph theory, decomposition methods...) in order to address multiple faults occurrence issues. I am also investigating the use of set-membership formalism and interval analysis approaches to deal with robustness against parameters and measurements uncertainties during the detection step by enhancing the decision making procedure. I have also developed monitoring strategies for robust and early detection of abnormal positions on aircraft control surfaces by dealing with parameters estimation approach.


  • K. TIDRIRI (Sep. 2015- present): Combining quantitative and qualitative modeling within an integrated approach dedicated for monitoring tasks of dynamic systems

  • I am co-supervising this thesis with S. Verron and T. Tiplica. The thesis defense is expected by the end of 2018. The proposed research work aims to develop a unified approach for dynamic systems integrated design within monitoring context. A first part is devoted to study the possibilities to develop a generic method that may enable to integrate data-driven approaches within the framework of the BRIDGE community. This work consists on proposing an original strategy by dealing with the tools and techniques that are used within the LARIS laboratory namely the Bond Graph approach and the Dynamic Bayesian network formalism. The second part of the proposed research work consists on exploiting the results emanating from the first part in order to address the prognostic tasks by focusing on the analogy that has been considered within the BRIDGE community when dealing with detection/diagnosis tasks.


    • Post-doctoral position

      My project (within the post-doctoral position) consisted on proposing robust fault detection strategies related to aircraft moving surfaces. Within this scope, a generic parametric strategy was proposed to deal with runaway failure case (a.k.a hardover) of aircraft control surfaces. A runaway is an uncontrolled deflection of a control surface which can go until its stops if it remains undetected. The methodology relied on a basic level which consists in parametric model estimation and decision test in parametric space, and a secondary level which is a bias estimator to improve the performance of fault detection. The proposed monitoring strategy is applicable to different kind of actuators as the method was based basically on black-box modeling and used no physical model of the actuator servo-control loop. The overall strategy satisfied technical requirements in terms of false decisions and detection time and it was implemented on a hydraulic actuator benchmark for real time fault detection and confirmation.

        InTraDE (Intelligent Transportation for Dynamic Environment is a European project which contributed in designing a new concept of Intelligent Autonomous Vehicles, able to handle and routing autonomously the freight transport in confined spaces of regional ports from North West Europe. The technological challenge issued from InTraDE consisted on proposing a safe, clean and efficient transport system which can easily be adapted to the existing port infrastructure, using different piloting modes. The aim is to improve significantly the traffic flow and the port logistics using sustainable solutions. My task within this project was to develop new methods and algorithms for robust supervision and to investigate model-based approaches for diagnosis.
