<P>PROBLEM TO BE SOLVED: To inhibit deterioration in controllability of an electric motor. <P>SOLUTION: When a control mode Cm is in a sine wave control mode or an overmodulation control mode and a torque command Tm* of a motor rapidly changes (S170, S190), an inverter is controlled by setting gains Kp1, Kp2 in proportionals and gains Ki1, Ki2 in integration terms based on the torque command Tm* and setting voltage commands Vd*, Vq* by a feedback control using the set gains (S210-S230). Further, when the control mode Cm is in a rectangular wave control mode and the torque command Tm* of the motor rapidly changes (S170, S240), the inverter is controlled by setting a gain Kp3 in a proportional and a gain Ki3 in an integration term based on the torque command Tm* and setting a voltage phase command θ* by a feedback control using the set gains (S260-S280). <P>COPYRIGHT: (C)2012,JPO&INPIT |
