    (IEEE, 2019) Ammar, Abdelkarim; AMEID, Tarek; AZZOUG, Younes; Kheldoun, Aissa; METIDJI, Brahim
    This paper presents an implementation of an efficient direct flux and torque control for induction motor drive. In control design, the modeling inaccuracy and various uncertainties cannot be avoided when classical methods are conducted. Therefore, it is recommended apply the nonlinear-robust control approaches to cover these drawbacks. The sliding mode approach is proposed to achieve a decoupled control and improve its robustness versus different disturbances. Furthermore, an optimal control algorithm is joined for losses minimization and efficiency maximization. This technique consists of the computation of optimum flux reference according to the load value and improves the efficiency for no load or light loads state, that makes is very suitable for variable load applications. The effectiveness of the control techniques is verified using an experimental test bench based on dSpace 1104 real-time interface
