PROBLEM TO BE SOLVED: To provide a control device for a multi-winding rotary machine that reduces an arithmetic load by simplifying a control structure of a decoupling part.SOLUTION: The control device is applied to a multi-winding rotary machine system comprising a multi-winding rotary machine including a plurality of winding groups of which the electrical specifications are equal to each other, a plurality of power converters that are provided for each of the plurality of winding groups, and a current detector. In the control device, a decoupling part 42 performs decoupling control operation for compensating a decoupling voltage caused by magnetic coupling. The decoupling part 42 "integrates" decoupling control items including mutual inductance and a current differentiation value relating to a controller post-command current of a concerned axis of another system with inverse model items relating to a controller post-command current of a concerned axis of its own system. The decoupling part further "integrates" decoupling control items including an angular velocity and self-inductance relating to a controller post-command current of a mating axis of its own system and decoupling control items including an angular velocity and mutual inductance relating to a controller post-command current of a mating axis of the other system. Thus, the control structure of the decoupling part can be simplified.SELECTED DRAWING: Figure 8 |
