CURRENT CONTROLLER FOR CRYOGENICALLY COOLED MOTOR

摘要

Current amplitudes in a motor can be controlled by summing a first signal indicative of an output current of the motor with a current command signal, integrating the current command signal with respect to time, and applying a first controller gain to a second signal indicative of the output current of the motor to obtain a gain-controlled signal indicative of the output current of the motor. The method further includes applying a second controller gain to the current command signal to obtain a gain-controlled current command signal, summing the gain-controlled signal indicative of the output current of the motor with the gain-controlled current command signal to obtain a voltage signal, and inputting the voltage signal to the motor such that current amplitudes in the motor are controlled.
