| 摘 要： | 为减少稳态转矩脉动，将滑模变结构控制方法应用于感应电机直接转矩控制。滑模控制可以根据磁链和转矩误差实际大小调节逆变器直流母线电压，并结合转矩预测控制合理的调节电压矢量的作用时间，从而有效地减少转矩脉动。仿真实验证明：即使电机运行在低速范围内，仍然能减少转矩脉动。

| Abstract: | In this paper, a sliding mode control method for direct torque control of induction motor is proposed, which is used to reduce the ripple of torque in stable state. Sliding mode control can adjust the voltage of DC bus according to the errors of flux and torque, which is then combined with the torque predict method to decrease the ripple of torque. The simulation result proved that even the motor run in low speed the effect is still good. |
