Original Abstract

In this paper, a simple parameter-independent adaptive method to compensate dead-time effects and nonlinearity of a inverter is presented. The proposed approach is based on the monitoring of harmonic distortion in the d-axis current. Consequently, the criterion is calculated and minimized. The output of the proposed adaptive method is one slowly time-varying voltage, which is used to compensate the output voltage distortion. This approach is extended by estimator of persistent voltage disturbance based on the model of the permanent-magnet synchronous motor (PMSM). The effectiveness of the proposed approach is verified through the simulation experiments.
