Abstract
PURPOSE: To optimize the preset value of the secondary resistance in the instantaneous reference computing circuit for the primary current through a good speed and magnetic flux control by following thereof to the genuine secondary resistance value of the induction motor.
CONSTITUTION: When an induction motor 2 is controlled employing a sine wave cyclo converter, the primary voltage and current of a motor 2 is detected and impressed on a secondary resistance R2 correction circuit 34 through 3-phase-2-phase convertion circuits 3 and 32. In the circuit 34, a secondary magnetic flux 2 is detected based on the w-phase signal and the output of a relative value computing circuit 14 and is compared with the result from the computation by a instantaneous reference computing circuit 18-2 whereby the value of the secondary resistance R2 set for the circuit 18-2 is controlled to make the magnetic flux computed equal to that detected. This enables change is the set value in the computation circtuit to match changes in the secondary resistance due to temperature change or the like.
