When permanent magnet synchronous motors (PMSM) are used in pump and fan applications where no excessive performance is required, the V/f scalar control method can be applied to enhance the ease of use for end users. For the voltage reference generation in V/f control, existing methods requires motor parameters such as the stator resistance, inductance, and back EMF constant of the permanent magnet, which is identified before or during operation. However, this paper proposes a simple and convenient V/f control method that utilizes the motor parameters given on the name plate. In the proposed method, stable operations are ensured for the rated speed and load ranges without position sensors. For successful starting operation, a DC current control loop is included to calculate the initial offset voltage reference for the V/f pattern. The stability and effectiveness of the proposed method are analyzed and verified by MATLAB/Simulink and 3.7 kW IPM motor drive experiments.

当在不需要过多性能的泵和风扇应用中使用永磁同步电动机（PMSM）时，可以采用V / f标量控制方法来提高最终用户的易用性。为了在V / f控制中生成参考电压，现有方法需要电动机参数，例如定子电阻，电感和永磁体的反电动势常数，这些参数在运行前或运行中确定。但是，本文提出了一种简单方便的V / f控制方法，利用铭牌上给出的电动机参数。在提出的方法中，在没有位置传感器的情况下，可确保在额定速度和负载范围内稳定运行。为了成功启动，包括一个直流电流控制环路，以计算V / f模式的初始偏置电压基准。通过MATLAB / Simulink和3.7 kW IPM电机驱动实验对所提方法的稳定性和有效性进行了分析和验证。
