In most variable-speed drives of PMSM, some type of shaft sensor such as an optical encoder or resolver is connected to the rotor shaft. However, such sensor presents several disadvantages such as drive cost, machine size, reliability and noise immunity. Therefore, the sensorless control of PMSM is desired and various sensorless control strategies have been investigated. This paper presents a novel sensorless control strategy for an interior permanent magnet synchronous motor (IPMSM). A new model of IPMSM using an extended electromotive force (EMF) in the rotating reference frame is utilized in order to estimate both of position and speed. The extended EMF is estimated by the least-order observer, and the estimation position error is directly obtained. The proposed scheme corrects the estimated position and speed so that the estimation position error becomes to be zero. The proposed system is very simple and the design of the controller is easy. Several drive tests are carried out and the experimental results show the effectiveness of the proposed sensorless control system.

@TK6A65D 森本による拡張誘起電圧の論文 https://t.co/gE2cgGaF7c のFig.3及び(14)から、(15)を導出すると、 パラメータ設計がわかるようになると思います。
拡張誘起電圧モデル+外乱オブザーバ方式のセンサレス制御における、位置・速度推定器へのPLL制御の適用ですが、Nakamura氏の指摘通り電気学会論文を見る限りは府立大が早かった匂いですね。厳密には産業応用やSPCを確認する必要ありますが。 https://t.co/CNAJWkCZVf
拡張誘起電圧とPLLについての話で欠かせないのが、 市川と同時期に森本からも類似(だがPLLの構造が違う)の内容の論文が発表されています。 https://t.co/JOFKoquKtO
