SPEED CONTROL OF PMSM BY USING DSVM -DTC TECHNIQUE
Journal Title: INTERNATIONAL JOURNAL OF ENGINEERING TRENDS AND TECHNOLOGY - Year 2012, Vol 3, Issue 3
Abstract
The Direct Torque Control (DTC) requires low computational power when implemented digitally for AC drives. The DTC possess good dynamic performance but shows quite poor performance in steady-state since the crude voltage selection criteria give rise to high ripple levels in stator current, flux linkage and torque. To reduce the problems with DTC the discrete space vector modulation method is proposed for DTC by applying more vectors in one interval. In this paper, after a brief review of the primary concept of DTC technique, a new scheme of DSVM DTC for PMSM is proposed with a new set of switching tables. Simulation on the proposed scheme is carried out and compared with basic DTC scheme.
