Supervision and Fault diagnosis of technical systems based on mathematical models

Model based fault diagnosis aims at detecting and isolating at an early stage the degradations in the operation of a technical system. It relies on the computation of fault indicators, also called residuals. The latter characterize the discrepancy between the data measured on-line on the supervised system and a mathematical model of this system describing its normal behavior or certain faulty behaviors. These indicators are processed in a so-called decision system in order to determine whether some of the residuals are significantly different from zero, and to deduce the most likely fault(s) from the pattern of zero and non-zero residuals.

Advanced control of nonlinear dynamic system subject to constraints. With emphasis on reference governor methods

The group specializes in the control of system subject to constraints through both predictive and non-predictive methods. The main goal is the development of new computationally efficient constrained control methods.

The main lines of research are:
– Command and Reference Governor Schemes
– NON-optimization Based Constrained Control Schemes

and their applications to:
– Aerial Robotics
– Distributed Systems (Power Networks)

Application domains

Electric energy production, distribution, and storage
Projects in electricity production and distribution aim at improving the availability of renewable energy sources, at accounting for the variability of renewable energy production in network security assessment and at ensuring ancillary services (see more).

Mechatronics (UAVs and robotics)
The goal is to develop control units for Unmanned Aerial Systems to enable the UAVs (quadrotors, multirotors, blimps, etc.) to interact with the environment and to perform operations (see more).

BrIAS Forum on War & Peace, and Robotics

4 avril 2024

The first day will focus on “Peace” and in particular how robotics can help to “clear up” remnants of war and ensure a safe restart of life at peace. The first half day will be focusing on the theme “A safer sea” and will mostly deal with marine demining, with a special attention to the innovation surrounding the Belgian Mine Counter Measures program. The second part of the day will deal with land demining. The second day will focus on “War”, and in particular on the Historical, Ethical, Legal, and Geopolitical aspects of Robotics at War. The goal of this second day is to inform the public about the current policies as well as the various different perspectives and positions on the matter, so as to stimulate an informed debate. Polemics for the sake of polemics and uninformed/acritical political statements should stay out of this day.

BrIAS Forum on Human-Robot Collaboration

4 avril 2024

Robots are becoming an integral part of our economy, society and planet, assisting us in various tasks. However, the rapid growth in robotics usage has also given rise to relevant concerns regarding sustainability. At present, urgent issues such as rare-earth material usage, e-waste, energy efficiency and ethical concerns hinders the sustainable development of robotics. As we increasingly rely on robotics, it becomes increasingly critical and urgent to ensure that these technological advancements are sustainable and eco-friendly. Since robotics is the integration of many technologies, we will discuss in this Forum sustainable robotics technologies ranging from material science, material processing and metal, electronics with sensors and processing, actuators, energy, power and batteries and control and artificial intelligence
