A new mains voltage observer for PMSM drives fed by matrix converters

Description

This paper presents a new Finite Control Set Model Predictive Control (FCS-MPC) algorithm with sensorless mains voltage detection, which has been applied to a Permanent Magnet Synchronous Motor (PMSM) driven by a Matrix Converter (MC). Unlike classical MC modulation methods, FCS-MPC allows direct control of the MC input currents. The mains voltage sensors elimination allows to increase the reliability of the system. The performance of the proposed work has been verified by simulation studies and experimental results.
