摘要:
A motor control system includes: a d-q target module configured to, based on a target torque of an electric motor, determine a first target d-axis current and a first target q-axis current; an offset module configured to, based on a capacitor current through capacitors connected across phases of the electric motor, determine a d-axis current offset and a q-axis current offset; an adder module configured to determine a second target d-axis current based on a sum of the first target d-axis current and the d-axis current offset and to determine a second target q-axis current based on a sum of the first target q-axis current and the q-axis current offset; and a driver module configured to, based on the second target d-axis current and the second target q-axis current, switch switches of a current source inverter (CSI) module configured to apply power to the phases of the electric motor.
