摘要
To eliminate the side impacts of inductance mismatch on the accuracy of finite control set model predictive current control (FCS-MPCC) scheme used for surface-mounted permanent magnet synchronous motors, this letter proposes a new flux observation transfer-based inductance identification strategy. First, a flux observer based on sliding mode theory is developed, with its stability analyzed. Second, the flux estimation errors are discussed, obtaining the relationship between the estimated flux and the inductance variations. On this basis, the inductance is detected using the flux information. Then, the estimated inductance is used to achieve the precise FCS-MPCC method. Finally, experiment is conducted on a three-phase SPMSM prototype to validate the proposed techniques.
