Control Method of Electromotor |
摘要 |
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.
