<P>PROBLEM TO BE SOLVED: To provide a controller for motor which reduces vibration even in decoupling control. <P>SOLUTION: This controller is equipped with a gain regulator 105, which converts the angular velocity ω[rad/s] of a rotor into gain-adjusted angular velocity ω'[rad/s] so that the gain in oscillation frequency of the angular velocity ω[rad/s] of the rotor may be reduced. The controller is equipped with a decoupling controller 104 which obtains a decoupling d-axis voltage command Vd[V] and a decoupling q-axis voltage command Vq[V], for decoupling control. The decoupling controller 104 obtains them, based on the gain-adjusted angular velocity ω'[rad/s], a d-axis PI output voltage command Vd'[V] and a q-axis PI output voltage command Vq'[V]. Furthermore, the controller is equipped with a PWM converter 109, which generates a PWM signal PWM for controlling an inverter 2, based on three-phase voltage commands Vu, Vv, and Vw[V] converted from the decoupling d-axis voltage command Vd[V] and the decoupling q-axis voltage command Vq[V]. <P>COPYRIGHT: (C)2009,JPO&INPIT |
