    • PROBLEM TO BE SOLVED: To provide a motor controller capable of driving a motor with high accuracy, even if a parameter fluctuates, when a motor driving voltage is calculated. SOLUTION: An angle calculating section 24 obtains an angle θ of a rotor, and an angle speed calculating section 25 obtains the angular speed ω e of the rotor. A command current calculating section 21 obtains command currents i d * , i q * on a dq axis, based on a steering torque T and a vehicle speed S. A correction voltage calculating section 26 multiplies the deviations the command currents i d * , i q * on the dq axis and between detection currents i d , i q detected by the current sensor 14 by a proportional gain etc. to calculate corrected voltages Δv d , Δv q . An open-loop control section 22 obtains command voltagesv d , v q on the dq axis, in accordance with a circuit equation of the motor, based on the command currents i d * , i q * and the angle speed ω e , and values added with the corrected voltages Δv d , Δv q are used as command voltagesv d , v q . A dq axis/three-phase conversion section 23 converts the command voltages v d , v q into three-phase command voltages. According to the command voltages, even if the parameters of the circuit equation vary, the motor can be driven with high accuracy. COPYRIGHT: (C)2010,JPO&INPIT
