The invention discloses an asynchronous motor model prediction direct torque control method, and relates to the technical field of motor control. Two control methods are improved through the mode of partition prediction and table lookup on the basis of comparative research of the performance of two control methods. According to the method, the system performance can be further improved, and the transient and steady-state torque ripple, stator flux linkage and current fluctuation of the motor can be significantly reduced. The simulation result proves that the torque, the flux linkage and the current fluctuation of the conventional DTC can be effectively reduced by the novel DTC strategy, the advantages of rapid response and simple control of the conventional DTC can be maintained and the control performance of the conventional DTC can be improved; meanwhile, vector selection is performed through combination of the partition table so that the dependence of finite model prediction controlon the model parameter accuracy can be reduced, and online computation of finite model prediction control can also be greatly reduced.
