    • A control method of the electromotor comprises: setting a target alternating axis current based on the rotor angular velocity of the electromotor and a target direct axis current based on the torque of the motor; simultaneously detecting three-phase currents and current rotor position angle of the electromotor; converting the three-phase currents to an actual alternating axis current and an actual direct axis current by Park and Clark conversions; inputting the difference between the target current and the actual current to a current loop, outputting the required direct axis current and the required alternating axis current; determining the three phase voltages according to the required direct axis current and alternating axis current and the angle of the electromotor rotor position; obtaining PWM control waveform through three-phase voltages, wherein said PWM control waveform is configured to control the conversion from direct current to alternating current and drives the electromotor.
    • 电动机的控制方法包括:基于电动机的转矩,基于电动机的转子角速度和目标直轴电流来设定目标交变轴电流; 同时检测电动机的三相电流和电流转子位置角; 通过Park和Clark转换将三相电流转换为实际交流轴电流和实际直轴电流; 将目标电流和实际电流之间的差分输入到电流回路,输出所需的直轴电流和所需的交变轴电流; 根据所需的直轴电流和交流轴电流以及电动机转子位置的角度确定三相电压; 通过三相电压获得PWM控制波形,其中所述PWM控制波形被配置为控制从直流到交流的转换并驱动电动机。
