Abstract

PURPOSE: To control a speed with high accuracy by a method wherein the time constant of a primary delay circuit can be corrected in accordance with a temperature change.
CONSTITUTION: An exciting current command value iM* derived from a magnetic flux regulator is fed into an integrator 2001, an output (x) of the integrator 2001 is fed to a multiplier 2002 where it is multiplied by a coefficient corresponding to the reciprocal 1/T2 of the time constant of a rotor circuit and then negatively fed back to an input circuit for the integrator 2001. In addition, the output of the multiplier 2002 is also taken out as an output (y) through a coefficient multiplier 2003. The output (y) conforms to the output of a primary delay element in the magnetic flux vector computer, while the output (x) conforms to the output of a proportional element. A temperature simulating circuit 206 calculates the temperature of a rotor from a stator winding temperature detected by a detecting end for the stator winding temperature, and the coefficient 1/T2 is changed in accordance with the temperature of the rotor conductor through a subtracting circuit 207, a coefficient multiplier 208, an adding circuit 209 and coefficient multipliers 210, 211.
