Dynamic and steady-state operation of a five phase induction machine with an open stator phase

Modelling and fault-tolerant control of 5-phase induction machine

“…In this paper the method based on back-EMF calculation presented in [14] is used for dynamic open phase-fault simulation which, in turn, allows to a clear depiction of the fault-tolerant algorithm application. Moreover, the dynamics issues of fault-tolerant control application may be crucial for high-reliability solutions.…”

“…Particularly, this paper presents method of phase lost modeling by calculation of back-EMF (instead of utilization of circuit breakers that allow for simulation of phase lost mainly in current zero-crossing condition). Although this approach was published previously in [14], neither the dynamic states nor fault-tolerant algorithm were presented. Several basic vector control methods for conventional three-phase induction machines have been developed in the last decades [15].…”

Post-fault operation of FOC-controlled 5-phase induction machine with hysteresis and PI+SVM current control

“…Unfortunately, 5-phase machine has another complex planes where losses are mapped and this has to be considered in case of modulation what will be developed further in this work. Finally, mentioned open-phase fault modelling method bases on calculation of back-EMF in faulted phase and was originally presented [14].…”

Effects of unbalanced voltage on the steady-state performance of a five-phase induction motor with three different stator winding connections

“…3 when k =1. If there is a fault, the machine currents are no longer balanced and it can be represented by five sequence decoupled circuits [16] - [19]. The relation between phase and sequence values can be defined as where 'f' represents either voltage or current and 'a' is defined as…”
