Current Control Strategy for the Sensorless Speed Control of Permanent Magnet Brushless Direct Current Motor
─ Brushless dc (BLDC) motor drives are continually gaining popularity in motion control applications. Therefore, it is necessary to have low cost, but effective speed/torque characteristics. A Brushless DC (BLDC) drives are known for higher efficiency and lower maintenance. As the name implies, BLDC motors do not use brushes for commutation instead, they are electronically commutated. For effec...
متن کاملSpeed Control of A Three Phase Current Forced Synchronous Machine Drive Based on A Simple Method
In this paper, a new method is proposed for the speed control of a three-phase current forced synchronous machine drive. This metohd is based on the use of an approximate constant commutation safety margin angle in the output thyristor bridge of the drive system as well as on the compenastion of stator magnetization reaction. The commutation process in the output converter of the machine driv...
متن کاملImproved Speed Estimation in Sensorless PM Brushless AC Drives
The application of flux-observer-based sensorless control to permanent-magnet brushless ac motor drives is described. Current methods of speed estimation are assessed, both theoretically and experimentally, and an improved method, which combines the best features of methods in which speed is derived from the differential of rotor position and from the ratio of the electromotive force to excitat...

متن کاملDSP-Based Sensorless Speed Control of a Permanent Magnet Synchronous Motor using Sliding Mode Current Observer
Received Jan 30, 2014 Revised Mar 2, 2014 Accepted Mar 18, 2014 In this paper, experimental results of 3-phase permanent magnet synchronous motor (PMSM) sensorless speed control are presented. To estimate the rotor position, a sliding mode current observer (SMCO) was implemented. This observer estimates the back emfs of the motor in the stationary reference frame using only the measured voltage...
