Abstract
A motor controller includes target current value generating circuitry that generates a d-axis target current value and q-axis target current value, motor current value generating circuitry that generates a d-axis motor current value and a q-axis motor current value of current supplied to a motor, command voltage value generating circuitry that generates a d-axis command voltage value from a difference between the d-axis motor current value and the d-axis target current value and a q-axis command voltage value from a difference between the q-axis motor current value and the q-axis target current value, command voltage value converting circuitry that converts the d-axis command voltage value and the q-axis command voltage value into three-phase command voltage values, and command voltage value modifying circuitry that modifies the three-phase voltage values based on motor flux values and target flux values.
