Abstract

PURPOSE:To correct variation of secondary resistance automatically and to realize a highly accurate vector control, by correcting a slip frequency command such that the difference between a torque current command and an actual torque current is zero. CONSTITUTION:A torque current operating unit 34 receives a secondary flux command phi' and a torque command tau and outputs a torque current command iq1'. A slip frequency correction signal omegaS is obtained through a controller 56 in order to match an actual torque current iq1 with the torque current command iq1' or in order to bring the difference to zero. The correction signal omegaS is added to a slip frequency omegaS0 operated through a slip frequency operating unit 55 in an adder 57 so as to produce an actual slip frequency command omegaS.
