Fault-tolerant control algorithms of switched-reluctance motor drive in open-phase modes

Nowadays is necessary to increase reliability and fault-tolerance of technical equipment that integrated in dangerous facilities such as both nuclear, military, chemical, petroleum etc. It is most pressing to electric drive mechanisms with full or partial functional recovery. In article shown fault-tolerant control algorithms of switched-reluctance motor drive in emergency modes. These algorithms based on activation of functional backup by either increasing phase currents amplitudes or increasing phases overlap angles or both of them. Under review the comparative analysis of these algorithms based on simulation in MatLab Simulink are shown. Full or partial functional recovery of switched-reluctance motor drive under single or multiple failures such as losing phase or converter switches failures are described.
