Model-free control

Participants : Cédric Join, Samer Riachy.

The achievements obtained in 2012 are as follows:

• The model-free control approach is applied to a complex nonlinear model describing the dynamics of a traffic flow in [24] . The robustness with respect to external disturbances is shown by numerical simulations.

• Model-free control is applied to a magnetic bearing in [56] , which is a quite important industrial device. The experimental results are compared to those obtained via other control techniques.

• ”Model-free” control and the related ”intelligent” proportional-integral controllers are successfully applied to freeway ramp metering control in [47] . Implementing the proposed control strategy is straightforward. Numerical simulations need the identification of quite complex quantities like the free flow speed and the critical density. This is achieved due to new estimation techniques, where the differentiation of noisy signals plays a key role.
