| 摘 要： | 分析传统直接转矩控制引起转矩脉动的原因,提出改进办法,用PI调节器代替滞环比较器,引入矢量控制的解耦思想和预期电压空间矢量调制方法。通过对一个完整的提升周期运行情况的仿真,结果表明:这种预期电压直接转矩控制能有效减小磁链和转矩脉动,更好地满足提升机的运行要求,具有实际意义。

| Abstract: | The reason for traditional direct torque control torque ripple is analyzed,using PI regulators instead of hysteresis comparator as a improving method.Meanwhile vector control decoupling thought and expected voltage space vector modulation are also applied.After the simulation of a complete hoist cycle,it can be proved that this method has effectively reduced flux and torque ripple and has practical sense. |
