Original Abstract

The paper focuses on a novel online dead-time compensation strategy for vector controlled permanent-magnet synchronous motor (PMSM). The proposed approach is composed of two parts. The first adaptive parameter-independent part is based on the monitoring of harmonic distortion in the d-axis current. Consequently, the criterion is defined as the sum of squared id current between two zero-crossing points of the phase currents. This criterion is minimized by PI controller and the output is slowly time-varying voltage, which is used to calculate the compensation voltages. This approach is extended by observer of persistent voltage disturbance that is based on the model of PMSM. The effectiveness of the proposed approach is verified through the simulations and experiments.
