A Study on Performance of Curent Regulations for IGBT Inverter-Fed Induction Motor Drive Systems

IGBT 인버터-유도전동기 구동시스템을 위한 전류제어기의 특성 연구

In this paper, a performance evaluation of different current regulators for induction motor drive systems fed by IGBT inverter is presented. The twoparts of current regulation are considered : current error compensation part, voltage modulation part. The characteristics of hysteresis, synchronous PI, decoupled PI, predictive, deadbeat and stage feedback controllers are analyzed and the steady-state performances and transient responses of current regulation are well compared through the simulation and experimental results.
