| 摘 要： | 为减少异步电机转矩脉动和定子磁链固定偏差，提出了一种改进的异步电机直接转矩控制策略。该策略是基于给定定子磁链幅值和角度的解耦控制，用瞬时转差角频率和转子角频率之间的关系来调节定子磁链给定角，而给定定子磁链幅值保持额定值不变。控制结构简单。通过Maflab6．5／simulink建立了仿真模型，仿真结果证实了该控制策略的有效性：

| Abstract: | A modified direct torque control strategy was proposed in order to reduce electromagnetic torque ripple and stator flux droop for induction motor.This method was based on decoupling control between amplitude and angle of reference stator flux.The relationship between instantaneous slip angular frequency and rotor angular frequency was used to adjust the the reference stator flux angle but the amplitude of the reference stator flux is always kept constant at rated value.The control structure is simple.The mo... |
