MRAS 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 کاملOn Position Sensorless Control for Permanent Magnet Synchronous Motor Based on a New Sliding Mode Observer
For the problems of buffeting and phase delay in traditional rotor detection in sensorless vector control of permanent magnet synchronous motor (PMSM), the Sigmoid function is proposed to replace sign function and the approach of piecewise linearization is proposed to compensate phase delay. To the problem that the output of traditional low pass filter contains high-order harmonic, two-stage fi...
متن کاملSensorless Vector Control for Permanent Magnet Synchronous Motor based on Estimation of Model Error
A method, which estimates the position of the rotor based on arithmetic model of the motor, is presented in this paper. In this method, mathematical mode of PMSM is regarded as reference model. By detecting the phase current of PMSM, the real position of the rotor of PMSM is calculated. And this method eliminates the parameters variation of the PMSM. Simulation and experimental results proved t...
متن کاملSensorless Permanent Magnet Synchronous Motor Drive : A Review
Vector control has been widely used in control of permanent magnet synchronous motors (PMSM) where the information of rotor position is required. Shaft position sensor such as an optical shaft position encoder or Hall Effect sensor is fitted to provide a signal that is used to maintain an appropriate space angle between the stator and rotor fields in the motor. Even though this method is very p...
