基于扩展磁链投影矢量观测器的无传感器直接转矩控制永磁同步电机驱动位置误差补偿策略

Accurate estimation of the stator flux is crucial for sensorless permanent magnet synchronous motor (PMSM) drives employing space vector modulation-based direct torque control strategy. However, the voltage–current hybrid model based adaptive flux observer suffers from increased position offset error due to the characteristics of the adaptive law and parameter mismatches. To solve the above-mentio...
