摘　　要：传统的电压源逆变器异步电机的矢量控制,定子电流的控制效果直接影响矢量控制性能,且对电机的参数变换很敏感。对此,提出了一种异步电机矢量控制的预测电流控制方法,来减小对参数解耦所造成的影响,保证异步电机矢量控制电流的跟随性能。研究结果表明,该策略能够有效地优化了矢量控制的动态响应,电流和转矩波动大大减少,并具有较强的鲁棒性。Traditional vector control of voltage source inverter asynchronous motor,the stator current control effect directly affects the vector control performance,and is very sensitive to the parameter transformation of the motor.In this paper,a predictive current control method of asynchronous motor vector control is proposed,to reduce the influence of parameter decoupling and ensure the current following performance of asynchronous motor vector control.Research results show that this strategy can effectively optimize the dynamic response of vector control,greatly reduce the current and torque fluctuations,and has strong robustness.
