THE METHOD FOR MODELING INDUCTION MOTOR USING PI CONTROLLER FOR TORQUE CONTROL

摘要

PURPOSE: A method for modeling induction motor using pi controller for torque control is provided to proceed concisely control of a drive system by getting a current command map through a simple modeling. CONSTITUTION: A speed of a motor is measured. A reference speed is inputted. The difference of speed and the base rate measured is calculated. An amount of change of the torque is calculated through the speed differential. The amount of change of the calculated torque is fed back to the motor. A signal outputted from an inverter(120) connected to the motor and the calculated torque variation amount are used. The speed of the motor is controlled.
