A novel estimation method for position and speed for the PMBLDC motor

A PM Brushless DC motor drive system is used to control the speed or the position of a Permanent Magnet Brushless DC motor. The position and speed sensors have some disadvantages such as increasing cost and reducing the drive robustness. By the reason, sensorless control has been studied for the last decades but the study has been still reminding problems. Therefore, a novel estimation technique for speed and position of PMBLDC motor is proposed. In the technique, the speed and position is calculated from estimated back-EMF which is estimated by only measurable voltages and currents of the PMBLDC motor.
