A Parallel Speed and Rotor Time Constant Identification Scheme for Indirect Field Oriented Induction Motor Drives

Rotor time constant identification is necessary for high-performance indirect field oriented control of induction motor drives. Meanwhile, speed sensorless technique has many advantages such as low cost and reduced hardware complexity. In recent years, the estimation methods for motor speed have respectively grown to maturity, but the research in the identification of rotor time constant remains t...
