Method for Improving stability of IPMSM Sensorless Control in Relation No Signal about High Frequency voltage

고주파 주입 신호가 없는 IPMSM 센서리스 제어 안정성 향상을 위한 방안

In this paper, it employs IPMSM sensorless methods about current model and Extend-EMF methods. By using a MATLAB/Simulink program, it presents sensorless method in relation No high frequency voltage and replaces current based sensorless method. This IPMSM motor is drived by MTPA and Flux weakening controls for adjusting a actual motor application. In order to improving stability of IPMSM sensorless control, method about Sensorless estimation change is suggested by this paper.
