Field Oriented Control of Multiphase Drives with Passive Fault-Tolerance
Description
Multiphase machines provide continuous
operation of the drive with no additional hardware in the
event of one or more open-phase faults. This faulttolerant
capability is highly appreciated by industry for
security and economic reasons. However, the steadystate
post-fault operation has only been feasible in
previous works after the fault localization and control
reconfiguration. Even though this is done at the software
stage, the obligation to identify the faulty phases and
store the modifications for every fault scenario adds
further complexity. This work reveals that this software
reconfiguration can be avoided if the field-oriented
control (FOC) strategy is designed to satisfactorily
handle pre- and post-fault situations. Experimental
results confirm the capability to obtain suitable postfault
operation without fault localization and control
reconfiguration, thus achieving a passive/natural fault
tolerance.
