To address the problems of traditional model predictivedirect torque control strategy, such as low computational efficiency, high voltage jump and poor steady-state characteristics, an improved model predictive direct torque control strategy is proposed. To improve the steady-state characteristics of the motor,36 virtual voltage vectors are constructed basedon the principle of the nearest three vectors. The action time of redundant vectors in the virtual voltagevector is adjusted by combining the principle of no beat. To prevent excessive voltage jump in the output line of the inverter from causing adverse effects on the motor, only voltage vectors with voltage jump not exceeding Ua/2 are selected as alternative voltage vectors. Meanwhile, the reference voltage vector is predicted by combining the model with the deadbeat principle,and the voltage vector located in the same sector as the referencevoltage vector is selected as the final candidate vector set. Compared with traditional control strategies under rated operating conditions, the experimental results show that the improved control strategy reduces the electromagnetic torque, stator flux amplitude error, and current harmonic distortion rate by 37.42%,32.00%,and 44.52%,respectively. The program execution time is reduced by approximately 11.52%.
