Automation and control systems

To maximize the contribution of hybrid electric vehicles (HEV) to the decarbonization of the transport sector, their energy performance is a key factor that needs to be considered from the design phase. For an HEV, optimizing the design in order to reduce consumption involves not only optimizing a sizing aspect but also the EMS. This co-optimization of sizing and energy management is generally tackled either by nesting optimal control algorithms within an optimization algorithm dedicated to sizing, or by using convex optimization to simultaneously optimize the design levels. However, the former approach is known to induce computational constraints (for example relating to calculation time), while the latter can affect modeling fidelity due to the constraints inherent in convex optimization...

Permanent magnet synchronous motors (PMSM) are a reference technology for electric vehicle propulsion. However, their large-scale deployment is subject to the constraints associated with magnets: the capacity to obtain resources as well as the environmental challenges related to mining, recycling and refining. In addition, PMSMs often require flux-weakening1 strategies in order to operate at high speeds, which can result in energy losses...

Like all sectors concerned by electrification, the transport sector requires the design of high-performance, efficient electrical systems that respond to multiple constraints, such as cost and compactness. In this context, optimisation has become an essential step in the design process of these systems, particularly for electrical machines...

Today, air quality is an issue of major concern when it comes to public health. To protect it, it is necessary to reduce emissions but also monitor global chemical changes taking place in the atmosphere. From the economic and safety points of view, it is also important to monitor industrial gas emissions. It was to tackle these different aspects that IFPEN’s researchers began developing a range of technological solutions, within the context of the Flair Suite™ project.

Electrification of the vehicle powertrain is one of the keys to sustainable mobility and hybridization with internal combustion engines is becoming increasingly common. In this context, the “48-volt” mild hybrid system is a low-cost, flexible and easy-to-integrate option, with reduced safety constraints and outstanding performances.

The rapid development of wind energy production depends, to a great extent, on improving its energy efficiency and its economic profitability. To maximize performance and operating life spans, the
