Abstract |
In this paper comparison on rotor position estimation method based on Hall-effect sensors and sliding mode observer (SMO) is presented. The estimation of phase or the rotor angle of Permanent-magnet Synchronous Motor (PMSM) is essential parameter which is required to control the drives. Due to low cost & wide ranging performance, Low-resolution Hall sensor is widely used in PMSM. Sliding mode observer is a sensor less technique for which control algorithm is implemented. As a result SMO has shown better performance during sudden load changing condition while under steady state condition Hall sensors shown better performance. At starting Hall sensors has sensed the rotor angle effectively but SMO has depressed in this area. Results of Matlab/Simulink have shown comparison of both angle estimation techniques at different situation | |||||||||
