Patent

CA 2372134

An integral term component generating unit 21 integrates a d-axis current difference AId and a q-axis current difference .DELTA.Iq using an integral gain Ki which is determined to stabilize a system where the d-axis current difference .DELTA.Id and the q-axis current difference .DELTA.Iq are multiplied by the integral gain Ki, integrated, and inputted, with respect to a steady gain M which approximates, including proportional gains Kp, the steady input-to-output relationship of a motor 2 to which the voltage applied to a d-axis armature and the voltage applied to a q-axis armature are inputted and from which the current flowing through the d-axis armature and the current flowing through the q-axis armature are outputted, thereby a d-axis integral term component Vd i which is an integral term component of a d-axis command voltage Vd_c and a q-axis integral term component Vq_i which is an integral term component of a q-axis command voltage Vq_c are generated.
