Abstract

PURPOSE:To lessen a disturbance factor and also to enhance the loop gain of a speed feedback loop by incorporating a feedback circuit of both a command current giving a secondary magnetic flux in the trans-vector control of an induction motor and a command current proportional to this current. CONSTITUTION:A line current of a motor 1 is detected by a current detector 10. Primary detection currents i1d' and i1q' which are a d-axis element and a q-axis element, respectively, that are rotating at an angular velocity omega0, are determined through computation from the line currents by means of a detection circuit 11. A feedback circuit is incorporated to vary a slip frequency command value omega0 with the difference between the detected i1q' and its command current i1q amplified at an amplifier 4 so that i1q is equal to i1q', and furthermore another feedback circuit is incorporated likewise so that the primary current command value of the d-axis element i1d is equal to its detection circuit i1d'.
