Current Control of Inverter-Fed Induction Motor Using Integral Variable Structure Control

적분형 가변구조 제어를 이용한 인버터 구동 유도전동기의 전류제어

A new current control technique for inverter-fed vector controlled induction motor drives is presented. Using a integral variable structure control(IVSC) approach, the current controller is designed in the stationary rotating reference frame. The chattering reduction technique is also considered by the full state flux observer. By employing the proposed control scheme, a good control performance is achieved in the transient and steady state. The effectiveness of the proposed scheme is demonstrated through the comparative simulations.
