基于Levenberg-Marquardt优化的永磁同步电机非线性及损耗补偿快速收敛改进MTPA控制

For permanent magnet synchronous machine (PMSM), maximum torque per ampere (MTPA) control is popular below rated speed, and deriving accurate control objective defined as the ratio of the torque to the stator current is critical to achieve high-performance MTPA control. However, the derived control objective can be greatly affected by the system nonlinearity and loss, such as core loss. This artic...
