PROJECT TITLE :

Controllability and Performance of a Nine-Phase FSPM Motor Under Severe Five Open-Phase Fault Conditions

ABSTRACT:

Fault-tolerant controllability for a nine-section flux-switching permanent magnet (NP-FSPM) machine underneath severe 5 open-section fault is presented during this paper. First, combos of extra degrees of freedom are derived to prove the high fault tolerance in the 9-part drive system. Second, angles between the adjacent healthy phases are used to categorize the 5 open-section fault cases, and stator-flux-oriented fault-tolerant management with harmonic current injection is developed to confirm the disturbance-free operation of the NP-FSPM machine drive. The main contribution is that the investigation on the effect of the reconstructed harmonic current components on the machine part currents and therefore the dynamic performance under varied switch transients. Additionally, some sensible hints are given for implementation, like the control degree of freedom, drive derating, and current control scheme. Experimental results are presented to validate the effectiveness of the sinusoidal current excitation and therefore the high dynamic performance of the NP-FSPM machine drive system.
