Design of variable structure current controller for induction motor drives

为定向磁场感应电动机驱动器设计了可变电流控制方案 .该电流控制器能快速响应参考值并具有可抗参数和干扰的稳定特性和较小的开关频率 ,增强了感应电动机驱动器的性能 .

In this paper, a variable structure current control scheme for field oriented induction motor drive is presented. The proposed current controller tracks reference value quickly, has robust property against parameter variation and disturbance, reduces switching frequency and improves performance of induction motor drive.
