Abstract
A motor controller obtains: a first motor target rotation number, a first motor actual rotation number of a first motor, a second motor target rotation number, and a second motor actual rotation number of a second motor; determines a first rotation number difference between the first motor target rotation number and the first motor actual rotation number of the first motor, and a second rotation number difference between the second motor target rotation number and the second motor actual rotation number of the second motor, determines first and second rotation control torques based on a smaller one of the first rotation number difference and the second rotation number difference; and determines a first motor torque of the first motor and a second motor torque of the second motor based on the first and second rotation control torques.
