Abstract

PURPOSE:To exactly simulate the magnetic flux of the motor for control by modifying, according to the change in temperature, the time constant of the primary delay circuit having the time constant which is to be equal to the electric time constant of a rotor circuit. CONSTITUTION:The torque part current target value iT of the transvector control device of the induction motor is given to a temperature simulating circuit 206 composed of a multiplier 2061, the primary delay elements 2062 and 2063 having different time constants and an adding circuit 2064 to calculate the temperature of a rotor conductor. Next, the difference from reference temperature is taken, a value corresponding to the electric resistance of the rotor circuit is outputted through the intermediary of coefficient units 208 and 209 and further is converted to the value corresponding to the time constant by a coefficient unit 211. And, it is inputted in the 2002 of the multiplier 200 of a transmission function circuit 200 to which an excitation part current target value iM is inputted and is made the output of the magnetic flux vector operator 20. Accordingly, the time constant of the rotor circuit can be set according to the change in temperatur and thereby the error of operation can be reduced to a large extent.
