Email this article Novel DTC-SVM for an Adjustable Speed Sensorless Induction Motor Drive
Abstract
This paper presents, the direct torque control (DTC) based space vector modulation (SVM) for an adjustable speed sensorless induction motor (IM) drive. This proposed system will give a clear study about DTC and SVM and the motor drive is supplied by a two-level SVPWM inverter. Based on input-output feedback linearization control the inverter reference voltage is obtained, using the IM model in the stator D–Q axes reference frame with stator current and flux vectors components as state variables. Moreover, a robust full-order adaptive stator flux observer is designed for a speed sensorless DTC-SVM system and a new speed-adaptive law is given. By designing the observer gain matrix based on state feedback H control theory, the stability and robustness of the observer systems is ensured. The speed adaptive stator flux observer stability guaranteed also by the gain matrix in very low speed. The experimental results are proved by simulation results.
