Abstract：In view of the asynchronous motor field-oriented vector control technique, the off-line iron loss compensation and on-line rotor time constant identification were studied to modify the control performance of asynchronous motor. Iron loss under different conditions, including the stator and rotor iron loss, have been measured by standard no-load test, and a function of iron loss changing with frequency and slip was derived. On this basis, to improve the traditional vector control, a system which contains iron loss compensation module was designed. Model reference adaptive method based on q-axis rotor flux was applied to achieve the rotor time constant online identification, using the rule that q-axis rotor flux equal to zero as a reference, adjusting the initial value of rotor time constant in the controller to improve the accuracy of the orientation angle of the rotor field. Simulation results show that the new scheme can provide a properly compensation of iron loss and the rotor time constant. The dynamic and the steady-state performance of the control system have been effectively improved.
