基于损耗准则获取的内置式永磁同步电机最大转矩效率控制

This article proposes a maximum efficiency per torque (MEPT) control strategy for interior permanent magnet synchronous motor (IPMSM) based on the acquisition of loss criteria. First, the characteristics and practical occasions of four different efficiency optimization strategies are theoretically analyzed. Based on the mathematical model of IPMSM considering iron loss, the extremum equation satis...
