Frequency converter control method and related equipment

The invention discloses a frequency converter control method and related equipment. The method comprises the following steps: acquiring a first torque set value of a first motor; a second torque actual value of a second motor is obtained, and the first motor and the second motor are motors in the same working system; determining an additional speed set value of the first electric machine based on the first torque set value and the second torque actual value; and controlling a frequency converter corresponding to the first motor based on the additional speed given value. According to the frequency converter control method provided by the embodiment of the invention, the first torque set value of the first motor and the second torque actual value of the second motor are acquired, the additional speed set value is determined according to the first torque set value and the second torque actual value, and the frequency converter corresponding to the first motor is controlled according to the additional speed set v
