摘要

This work highlights the robustness and good performances of sensorless induction motors using a novel control strategy that combines backstepping with high-order sliding mode control, that’s integrate the super twisting algorithm. To demonstrate the superiority of the proposed control strategy in motor performances, it will be compared to three other nonlinear controls applied to the same motor under the same operating conditions; namely; second-order sliding mode control, conventional backstepping, and integral backstepping control. Additionally, to verify the robustness of the new control against internal parametric disturbances of the motor, a sudden increase in rotor resistance value will be imposed on all four studied controls under the same operating conditions and at the same time. Furthermore, to avoid the drawbacks of mechanical speed sensors, a sliding mode observer for motor speed will be studied, designed, and applied to the different installations. For a more objective critical analysis of the aforementioned controls, several simulations will be presented in the MATLAB/SIMULINK environment to shed light on the motor’s behavior under different constraints for each control method.
