磁场定向的异步电动机最佳效率控制

Optimal-efficiency Control of Asynchronous Motor for a Field-oriented Frame

本文提出了一种变速、变转矩下使电机功率损耗最小的方法，该方法适用于通用磁场定向控制的异步电动机驱动系统。仿真结果表明，所提方法是正确的。

In this paper an approach is proposed that minimizes the losses in a variable torque and speed asynchronous motor drive. This method is referred to asynchronous motor drive for a conventional field-oriented frame. Simulation results are presented to validate the proposed method.
