针对永磁同步电机模型预测转矩控制权重系数设计和调节的问题，采用标幺化成本函数将控制目标转换为无量纲的变量，从而消除权重系数，仿真验证其有效性。研究指出标幺化成本函数统一控制目标的变化范围，仅适用于所有控制目标重要性基本相同的领域，并且计算量大，算法实时性降低。

Aiming at the problem of weighting factor design and adjustment of model predictive torque control (MPTC) of permanent magnet synchronous motor (PMSM), the pre-unit cost function is used to transfer the control objects into dimensionless variables, so as to eliminate the weighting factor, and its effectiveness is verified by simulation. Studies show that the pre-unit cost function unifies the range of control objects, and it can only be used in the area where the importance of all control objects is almost the same, and its computational load is large, and its real-time performance of the algorithm is reduced.
