摘要：

This paper presents an effective online approach for dead-time compensation using a simple vectorial disturbance estimator in permanent-magnet synchronous motor (PMSM) drives. The proposed estimator can calculate the disturbance voltages, which are induced by dead time, by the use of simple vector operations, i.e., the inner and outer products of flux linkage increments and a unit back electromotive force function. Then, to compensate the effect of dead time, the estimated disturbance voltages are feedforwardly added to the current control loop. This method is applied to the 750-W laboratory PMSM drive to show its effectiveness.
