Abstract
PURPOSE:To remarkably improve the variable speed controlling performance of a motor, by using vector control by a current model method, and a voltage model method together. CONSTITUTION:By using a torque command value gamma from a speed regulator 8 and a magnetic flux command value PSI from a magnetic flux command unit 9, from a controller B including a current model, the output of current compo nent command values iM, ir, a magnetic flux angle speed omega1, and the estimate phiof a magnetic flux axial-position angle is generated. From a regulating means 22, the output of a correction value R2 to permit the arithmetic output value eo of an arithmetic means 21 to coincide with is generated. Then, a secondary resistance value used for performing arithmetic calculation approximates a true value, and as its result, a magnetic flux axial-position estimated by the current model coincides also with a true value in a motor.
