| 摘 要： | 建立了感应电机直接转矩控制(DTC)系统、模型预测转矩控制(MPTC)系统、基于占空比调制的DTC和MPTC系统仿真模型，并对四种控制策略进行仿真对比。仿真结果表明：控制性能上，基于占空比调制的MPTC>MPTC>基于占空比调制的DTC>DTC。通过转矩无差拍控制对电压矢量占空比优化调制，可有效减小转矩脉动，提高控制性能。 |

| Abstract: | The four simulation models of induction motor direct torque control (DTC) system, model predictive torque control (MPTC) system, the DTC system based on duty cycle modulation and the MPTC system based on duty cycle modulation are established. The comparisons of different control strategies are carried. Simulation results show that in terms of control performances, the MPTC based on duty cycle modulation>the MPTC>the DTC based on duty cycle modulation>the DTC. The duty cycle modulation based on torque deadbeat control can not only optimize the duty cycle of voltage vector, but also decrease torque ripple and improve control performance. |
