Super-twisting sliding mode controller for freeway ramp metering

Colloque avec actes et comité de lecture. internationale.International audienceIn this paper we propose a new feedback controller for freeway ramp metering. It is based on a second order sliding mode technique called super twisting sliding mode controller (STSMC). It is a simple and robust controller. It is less sensitive to parameter values and the model uncertainty with less problem of chattering phenomenon compared to the first order sliding mode controller. And then, this new controller is compared with a well known feedback controller for freeway ramp metering called ALINEA. The simulations show a good result of the new controller for freeway ramp metering. Moreover, compared to ALINEA, the STSMC can cope better the system in term of robustness and uncertainty
