Many commercial and military transport systems have fault diagnostic functions implemented to help protect the device when a severe fault occurs. However, most present systems do not contain prognostics capability which would allow operators to observe an unhealthy system component in its prefault condition. In industry applications, scheduled downtime can result in considerable cost avoidance. The next technology step is self-healing system components which observe not only potential problems, but can also take steps to continue operation under abnormal conditions -whether due to long-term normal wear-and-tear or sudden combat damage. In this paper, current and voltage information using the double-layer gate drive concept is fed to intelligent networks to identify the type of fault and its location. These intelligent networks are based on unsupervised and supervised learning networks (self-organizing maps and learning vector quantization networks respectively). The proposed concept allows the reconfiguration of the electric machinery system for continued normal operation of the machine. This paper presents an intelligent health monitoring and self-healing control strategy for a multi-phase multilevel motor drive under various types of faults.

“…References [11,12] focus on the fault modes of the two-channel induction machines under sinusoidal supply. However, these and similar publications do not take into consideration the influence of spatial harmonics of the magnetomotive force (MMF) caused by the non-sinusoidal distribution of winding turns in space.…”

This paper focuses on analyzing asymmetric and open-phase fault modes in symmetrical two-channel six-phase induction machines while considering the spatial harmonics of the electromagnetic field in the air gap. Under sinusoidal power supply, the magnetomotive force exhibits high-order spatial harmonics, which arise due to the winding design. The interaction between these spatial harmonics and the first-time harmonic of the power supply results in the presence of high-order harmonics in the current and electromagnetic torque. The harmonic content of the currents and torque under asymmetric and open-phase operation mode while taking into account spatial harmonics is analyzed. It is shown that in asymmetrical modes, in addition to the 5th, 7th, 11th, and 13th higher harmonics found in symmetrical modes, harmonics in multiples of the 3rd are introduced into the stator winding currents. As for the composition of the electromagnetic torque in asymmetrical modes, all even harmonics are present, in addition to the 6th and 12th harmonics that are characteristic of symmetrical modes. A mathematical model of the six-phase induction machine has been developed using the average voltages within the integration step method. Its adequacy was verified by comparing the simulation results with the experimental results obtained from the developed prototype.

“…Among the numerous possibilities of multi-phase AC machines, the six-phase induction machine (6PIM) is probably the most popular in industrial applications. A modelling approach of the 6PIM with one or more open phases has been presented in [1] [2] showing the importance of torque oscillations that affect the machine performances [3]. In order to solve this problem, it has been proposed to closely relate it to the control techniques used in the drive [4]- [6].…”

In this paper, a new fault tolerant direct torque control (DTC) algorithm for six phase induction machines (6PIM) is introduced. The machine presents two sets of three phase windings spatially shifted by 60 electrical degrees. The aim of the proposed approach consists in computing an average stator voltage vector in order to control the mean values of the stator flux and the electromagnetic torque over a sampling period under open phase. The main advantages are fixed switching frequency, low torque ripples and reduced line current ripples in comparison with classical DTC. Simulation and experimental results show satisfying performances and validate the proposed method.
