Running over the motor rated speed is crucial in applications, such as electric vehicles. The flux weakening technique for reaching high speed used in this article is model predictive control (MPC) based control. The method ensures that the induction motor operates far above its normal speed, however, there are significant issues, such as ripple in terms of speed, torque, flux, etc. A novel sliding mode control (SMC) is suggested in this article to both improve induction motor control performance and get rid of the drawbacks of MPC-based flux control. The study findings revealed that the chattering problem has been solved significantly as well as improving the speed and torque control performance. By including the exponential and constant rate elements, new SMC technique has been developed to address the chattering issue. The time to reach the steady state in speed is decreased using the suggested adaptive terminal SMC technique, and the chattering issue is resolved. The simulation and experimental results show that the suggested adaptive terminal SMC approach reduced ripple and chattering issues while improving other factors like error reduction and time to steady state in speed. In addition to enhancing the motor control performance, less total harmonic distorsionof the motor current, flux, and torque ripple are achieved.
