This research focuses on controlling the speed of the induction motor by applying an improved scalar control method. Scalar control techniques are typically employed in medium-level industrial performance applications and are characterized by maintaining a constant voltage-to-frequency ratio throughout the control process. The drawback of scalar control methods is that the motor operating speed is consistently lower than the set speed due to the rotor slip phenomenon in the control process. This research proposes combining the synchronous and virtual rotor speeds to compensate for rotor slip losses during motor speed regulation. A current model is proposed for generating synchronous speed, and the Current-Based Model Reference Adaptive System (CB-MRAS) for the virtual rotor speed applies to the compensation algorithm in closed-loop scalar control. The slip compensation value is updated during each setting cycle, ensuring consistent control performance even with load variations during operation. The effectiveness of this control approach is demonstrated through simulations, where it is compared with conventional methods under various operating conditions.
