Abstract
This paper proposes a space vector control of permanent magnet synchronous machine (PMSM) based on Hall effect sensor, which is very useful in practical applications due to the exactly same hardware structures between PMSM and brushless DC (BLDC) machine. This proposed method can be considered as an intermediate stage of development between the general incremental encoder based and sensorless based PMSM control methods. Because the Hall effect sensor is an absolute position sensor with 60-degree resolution, the position initialization process is not needed and the reversal rotation risk can be avoided. To improve resolution the interpolation method implemented by software is employed. Finally the high performance of this proposed method is validated by some experimental results.
