求翻译：大部分文献中，永磁同步电机DTC控制过程中磁链的参考信号均为定值，磁链给定的不合适会影响到输出转矩不够或者产生过多损耗等问题，而且磁链参考为定值就不能实现电机定子电流的最优控制，而在一定的工作情况下，定子电流的最优控制对于提高系统的效率、降低损耗等具有很大意义。本文结合矢量控制中定子电流最优控制方法与直接转矩控制特点，通过转矩参考信号计算给定磁链，实现了定子电流的优化是什么意思？

Most of the literature, permanent magnet synchronous motor in flux dtc control process are the reference signal value, inappropriate given flux will affect the output torque is not enough or excessive wear and tear issues, and flux reference is value can not achieve optimal control of stator current
