minimum stator current 最小定子电流
This method is to control the stator current as a vector quantity on the basis of slip frequency control. 在这一控制方法中,定子电流在转差频率控制的基础上作为一个矢量进行控制。
Simulation results showed that this control strategy can decrease the stator current anti improve the efficiency of the system. 仿真结果表明永磁同步电动机直接转矩控制系统最大转矩电流比控制可以降低定子电流，减小损耗，从而提高系统效率。
It can realize automatic tracing and automatic mpensation so as to increase power factor of the motor,reduce temperatures of stator current and the motor. 该系统实现自动跟踪、自动补偿以达到提高电机功率因数,降低电机定子电流、电机温升等目的。
When the motor is operated in low speed range, the stator current is discontinuous, and then the back emf can be detected directly while the stator current is zero. 当电动机操作在低转速范围时，定子电流为不连续，可在电流为零处，直接侦测反电势。
In U-I model, the measurement of stator current will influence the EMF, and finally the magnitude and phase of flux, resulting in the inaccurate orientation, bad performance and instability. U-I模型中，定子电流的检测精度势必影响到电机反电动势的计算，最后影响磁链的大小和相位，导致磁场定向不准确，系统性能不好，工作不稳定。
First, a simple rotor position estimating technique is presented.By measuring the stator current and compensating for the influence of the back EMF, the rotor position and velocity can be estimated. 首先，提出一种简单的转轴角度估测方法，经由侦测定子电流，并适当地补偿电动机的反电势的影响，即可准确估测永磁同步电动机的转轴角度与速度。

On the other hand, when the motor is operated in middle to high speed range, the stator current is continuous.The back emf can be computed.Finally, the rotor position can thus be obtained. 当电动机操作在中、高转速下，定子电流为连续时，可经由计算求出反电势，以获得电动机的转轴角度位置。
