초록

This paper presents a design and implementation of DSP-based full-digitalized sliding mode controller(SMC) for an induction motor(IM) fed by voltage source inverter(VSI) with intelligent power module(IPM). By using SMC with load torque observer, we can obtain improved control performances, i.e., robustness, high precision and low chattering. Furthermore, this paper emploies space vector modulation (SVM) method which is implemented to minimize hard ware configuration and to obtain modulation flexibility along with only DSP software operation.
