Real Time Implementation of Backstepping Control for High Performances Induction Motor Drive

This paper describes a nonlinear control of the induction motor (IM) drive. The control strategy is based on backstepping approach in order to ensure a high performance of speed control and a better dynamic under uncertainties and external disturbances. The backstepping nonlinear control is developed using a non-linear law for currents, speed and flux, instead of vector control strategy. The performances of this control strategy have been examined through simulation and experimental results, using Matlab/Simulink and dSPACE system with DS1104 controller board. Obtained results show the robustness of the control algorithm for both load disturbances and speed variation.
