Abstract

This paper treats the traction control in electric vehicle driven by a doubly fed induction motor (DFIM). A robust nonlinear control law at the torque level is presented to cope with the unknown tire reaction force. A parameter estimation function is computed for the adaptive control of the system with unknown friction forces. The consequent generated torque control law is implemented in the DFIM. A vector control technique of a DFIM is proposed. The approach is based on a flux orientation of the rotor with scalar control on the stator. The control strategy achieves the aim of traction control and maintains the slip ratio at constant value 0.2 when road surface varies.
