<P>PROBLEM TO BE SOLVED: To provide a controller for permanent magnet type rotating electrical machine, which derives the amount of correction of an error dependent on the number of revolutions included in the detected position of a magnetic pole, an error in attachment, an error due to secular change, and an error due to dispersion of products. <P>SOLUTION: A controller for permanent magnet type rotating electrical machine executes the processing of dq vector control by setting the amount of positional correction of a magnetic pole to a predetermined temporary set value, while keeping both a d-axis current command and a q-axis current command in dq vector control zero on a dq coordinate system, where the direction of the field of a rotor is d axis and the direction orthogonal to the d axis is q axis, in each state where the rotor is rotating in two or more roughly constant numbers of revolutions. It computes an error, based on a predetermined operational expression where the d-axis voltage command and the q-axis voltage command are parameters, from the d-axis voltage command and the q-axis voltage command obtained at execution of dq vector control, and derives number of revolutions-error properties, based on the error in each state and the number of revolutions at that time. Furthermore, based on the number of revolutions-error properties, it gets the amount of positional correction of the magnetic pole geared to the number of revolutions of the rotor for correcting the detected position of the magnetic pole. <P>COPYRIGHT: (C)2010,JPO&INPIT |
