In this paper we propose to design a robust control using sliding mode for double-fed induction machine (DFIM), the stator and rotor are fed by two converters. The purpose is therefore to make the speed and the flux control resist to parameter variations, because the variation of parameters during motor operation degrades the performance of the controllers. The use of the nonlinear sliding mode method provides very satisfactory performance for DFIM control, and the chattering effect is also eliminated by the function "sat". Simulation results show that the implementation of the DFIM sliding mode controllers leads to robustness and dynamic performance satisfaction, even when the electrical and mechanical parameters vary.
