Abstract

PURPOSE: To control the motor stably by making the average in the commutation period approximately equal to a commanded value on detecting a secondary flux of the motor and a slip anlular velocity of the rotor to the commanded value of the slip angular velocity.
CONSTITUTION: When the secondary flux vector rotates counterclockwise while the primary current vector is in the A-direction at the time tO, that is, a signal "1" of the counter 205 is provided to P1, the slip angular velocity ws becomes less gradually, an input signal e to the level detecting circuits 201, 202 increases, and the circuit 201 emits a signal eU of a constant level when the signal e exceeds the reference signal eO. The pulse generator 203 gives an count-up signal PU to the counter 205 by the rise of signal eU, a signal "1" is delivered form P at the time t1 to commutate the thyristor at the time t2, the primary current vector is jumped in the B- direction. In the case of opposite direction to this, an output signal eD from the circuit 202 causes the same operation. Thus a stable control can always be performed.
