PMSM DTC drive system fed by fault-tolerant inverter connected to a photovoltaic source

In this paper experimentation fault-tolerant control for Permanent Magnet Synchronous Motor (PMSM) drive system fed by a three phase inverter connected to a photovoltaic source is presented. PMSM drive system requires uninterrupted and safer conditions during operations. Therefore the diagnostic of voltage source inverter (VSI) and PMSM faults are needed to improve the availability of the system. This article aims to propose an accurate open-phase fault detection and fault-tolerant inverter of a DTC PMSM. The experimental implementation is carried out on powerful dSpace DS1104. The validity of the proposed method has been experimentally verified.
