The scientific organization of the Compiegne Electric Drives Laboratory is centered around only one field of competences, heading:

“Electric Actuators and motricity systems with embedded energy “.

The objective is to reinforce the position of the LEC, as pole of competence in the field of the global design of the actuators with electronic control. It is a field which requires to control aspects various like electromechanics, the control electronics, and also the constraints related to thermics and acoustics. Accordingly, the activities were redeployed under two complementary sets of themes, entitled respectively:

Design, modeling and optimization of the electric actuators

The objective of the set of themes “Design, modeling and optimization of the electric actuators” is to study the electric actuators presenting an innovative character at the structure level (machine, power electronics and control), as well as conditions of use of more traditional structures. This axis requires a scientific and technological multi-field approach associating electrical engineering, the power electronics, the control, thermics, mechanics, as well as mathematical tools for the numerical analysis and optimization.

Electric supply of embedded systems

The constant search for an increase in autonomy of the systems with embedded energy imposes a dimensioning and an optimal control of the actuators, but also of their feeding system. Two actions will be developed in this set of themes:

  1. Pulses Width Modulation Strategies (MLI or PWM)
  2. Modeling of electrochemical devices adapted to the Electric Engineering.
