MRAS based Speed Control of sensorless Induction Motor Drives
Senseless induction motor drives are widely used in industry for their reliability and flexibility, particularly in hostile environment. However, the performance of many of previously developed observer based speed sensors in very low speeds of IM drives was not satisfactory. In this paper we present two types of MRAS based speed estimators, one based on the rotor flux and the other based on th...

New speed and current estimation techniques are presented. These are used to formulate a single current sensor based vector controlled drive. The proposed method i...
متن کاملA Novel MRAS Based Estimator for Speed-Sensorless Induction Motor Drive
In this paper, a novel stator current based Model Reference Adaptive System (MRAS) estimator for speed estimation in the speed-sensorless vector controlled induction motor drives is presented. In the proposed MRAS estimator, measured stator current of the induction motor is considered as a reference model. The estimated stator current is produced in an adjustable model to compare with the measu...
متن کاملA Comparison of Induction Motor Speed Estimation using Conventional MRAS and AI- Based MRAS with a Dynamic Reference Model
− The Model Reference Adaptive System (MRAS) is probably the most widely applied speed sensorless drive control scheme. This paper compares induction motor speed estimation using conventional MRAS and AI-based MRAS with Stator Resistance Compensation. A conventional mathematical model based MRAS speed estimation scheme can give a relatively precise speed estimation result, but errors will occur...
متن کاملSensorless Speed Based on MRAS with Tuning of IP Speed Controller in FOC of Induction Motor Drive Using PSO
In this paper, a field oriented control (FOC) induction motor drive is presented. In order to eliminate the speed sensor, an adaptation algorithm for tuning the rotor speed is proposed. Based on the Model Reference Adaptive System (MRAS) scheme, the rotor speed is tuned to obtain an exact FOC induction motor drive. The reference and adjustable models, developed in stationary stator reference fr...
