The invention relates to the field of servo control, and provides a method and a device for determining a dead time compensation value of an inverter. The method comprises the following steps: determining a three-phase current instruction in a current control loop of the servo system and an actually measured dead zone characteristic curve corresponding to an inverter in the servo system; determining a dead-zone time compensation value of the inverter based on the three-phase current instruction and the actually measured dead-zone characteristic curve; and determining a dead-zone compensation coefficient, and determining a final dead-zone time compensation value based on the dead-zone compensation coefficient and the dead-zone time compensation value. According to the method and the device, the error compensation phenomenon can be avoided to the greatest extent, and the accuracy of dead time compensation is effectively improved.
