Model Reference Adaptive System (MRAS) Based Speed Sensorless Vector Control of Induction Motor Drive
This paper presents a Model Reference Adaptive System (MRAS) based speed sensorless estimation of vector controlled Induction Motor Drive. MRAS based techniques are one of the best methods to estimate the rotor speed due to its performance and straightforward stability approach. Depending on the type of tuning signal driving the adaptation mechanism, MRAS estimators are classified into rotor fl...
متن کاملMRAS 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...
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 کاملMRAS Based Sensorless Control of Permanent Magnet Synchronous Motor
Speed and torque controls of permanent magnet synchronous motors are usually attained by the application of position and speed sensors. However, speed and position sensors require the additional mounting space, reduce the reliability in harsh environments and increase the cost of a motor. Therefore, many studies have been performed for the elimination of speed and position sensors. This paper i...
متن کاملHybrid Pwm Based Mras Speed Observer for Sensorless Control of Induction Motor Drive
This paper presents a novel method of Hybrid pulse width modulation (HPWM) algorithm for control of induction motor drive based on model referencing adaptive system (MRAS). In the conventionally used space vector pulse width modulation (CSVPWM) scheme the duration of zero voltage application is equally distributed in each and every sampling period. In this is paper a HPWM is presented for senso...
