Abstract
This paper proposes a sliding-mode observer based rotor flux estimation scheme for induction motors. The sliding-mode observer is designed to track the stator currents and the control signals of the observer are used to estimate the rotor flux. The proposed rotor flux estimation scheme utilizes the stator currents, but does not need the stator voltage. It has significant advantages in practical applications, especially for sensorless Field Oriented Control (FOC) of induction motors. Some simulations are carried out to validate the proposed rotor flux estimation scheme.
