<P>PROBLEM TO BE SOLVED: To provide a nevel rotary machine controller that controls control amounts having at least one of current flowing in the rotary machine, torque, and magnetic flux by switching on and off a switching element of a DC-to-AC converting circuit. <P>SOLUTION: An operation state (voltage vector) in which an evaluation function J obtained by adding an offset value Δ to the inner product of the difference between predicted currents ide and iqe predicted by a predicting unit 33 and the difference between vectors idr and iqr of a command current is the minimum is determined as the operation state of an inverter IV. At the time of rectangular wave control, the offset value Δ in the evaluation function J for states other than an operation state according to a phase determined by torque feedback control is increased. <P>COPYRIGHT: (C)2013,JPO&INPIT |
