基于双状态磁链估计的永磁同步电机温度不敏感不可逆退磁故障诊断

This article proposes a temperature-insensitive irreversible demagnetization (ID) fault diagnosis based on dual-state flux estimation for permanent magnet synchronous motors considering temperature influence. The methodology employs dual-state extended state observers (ESOs) to accurately capture system disturbances and compute the real magnetic flux through full-rank fourth-order discrete equatio...
