Abstract
A controller for a multiplex winding motor. When a multiplex winding motor is driven and controlled by inverters and each winding includes a current control system, the controller compensates interference between the current control systems of windings. Voltage non-interacting arithmetic sections compute a voltage command value supplied to voltage applying sections, which are connected to a set of windings, not only by using an output value of a current control section for controlling current in one winding but also using an output value of a current control section for controlling current in another winding, so that voltage interference between the current control sections is compensated.
