Estimation Of parameter For Induction Motor Drive

چکیده
Generally speed measurement is done with sensor, but disadvantage of sensor is difficult to measure speed at low speeds with sensor. These difficulties are eliminated by using sensor less Flux Orientation Controlled (FOC) . This paper proposes a Model Reference Adaptive System (MRAS) for estimation of rotor speed in FOC. An Induction motor is developed in stationary reference frame and Space Vector Modulation (SVM) is used for inverter design.PID controllers are designed for this FOC. It has good tracking and attains steady state response very quickly which is shown in simulation results.
