Sensorless Speed Control of Induction Motor using Model Reference Adaptive System and Deadbeat Regulator

This paper presents the sensorless speed control of induction motors utilizing the Model Reference Adaptive System (MRAS) method and field-oriented control. The core objective is to minimize the cost related to speed sensors, thereby improving both the affordability and efficiency of motor control. Elimination of the sensor is achieved by estimating the rotor's angular speed, and the MRAS approach offers a sturdy alternative for this purpose. The presented approach provides a robust alternative, where the adaptation mechanism is facilitated by the implementation of a Deadbeat regulator. This mechanism allows for an improved response and superior control in motor operations, thus making sensor-based systems less necessary. In order to ascertain the efficiency of the proposed method, a comprehensive simulation test was conducted using MATLAB/Simulink.
