Abstract: Aiming at the problem of control performance degradation caused by motor parameter error in model predictive control, a step identification strategy was presented according to the influence of different parameters on the motor. The inductance and flux were identified by model reference adaptive control, and then the stator resistance was identified. The simulation results show that the proposed method can accurately identify multiple parameters of the motor, and ensure that the control performance of the model predictive control will not deteriorate due to the change of parameters.
