積分フィードバック形速度推定法併用の固定座標4次同一次元状態オブザーバによるPMSMの新センサレスベクトル制御法

抄録

This paper proposes a new sensorless vector control method for permanent-magnet synchronous motors (PMSM), which uses a new full-order (4th order) state-observer in stationary reference frame combined with the “integral-feedback type speed estimation method". The proposed method can be applied to both of salient and nonsalient PMSM.
