基于直流侧功率测量的内置式永磁同步电机最大转矩电流比控制

Maximum torque per ampere (MTPA) control scheme for buried magnet permanent magnet synchronous motor (PMSM) or internal permanent magnet (IPM) machine is presented in this paper. The proposed control scheme was developed based on measurement of only dc-link quantities eliminating the necessity of three-phase current feedback. The scheme employs an online search algorithm with initial condition com...
