“…It can be observed from equation (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12) that there is a relationship between the magnitude of the torque current and the slip speed. Assuming that the rotor resistance does not change significantly as the machine runs, and that there is a constant air gap flux density in the machine, then there is a constant relating the torque current to the slip speed.…”

“…Induction machines with more than three phases, referred to as multiphase or high phase order induction machines, have also been introduced mainly for specialized applications like in moreelectric aircraft [7]- [9], electric ship propulsion [10]- [13], electric vehicles [14]- [16] and in renewable energy applications [17]- [18]. A literature review of the previous work related to multiphase machines with a special focus on induction machines is presented in this chapter.…”

The rotor position is obtained through tracking the saturation saliency by measuring the dynamic currents responses of the motor due to the IGBTs switching actions. It uses the fundamental PWM waveform obtained using the multi-phase space vector pulse width modulation only. The saliency tracking algorithm used in this paper doesn't only improve the quality of the estimated position signals but also guarantees a minimum current distortion through reducing the modifications introduced on the PWM waveform. Simulation results are provided to verify the effectiveness of the proposed strategy for saliency tracking and current distortion minimizing of a five-phase PMSM motor drive over a wide speed ranges under different load conditions.

This paper introduces a novel technique to maintain the operation of the five-phase Permanent Magnet Synchronous Motor (PMSM) post the failure in two phases of the motor and post the failure of the speed sensor occurs simultaneously. To achieve that, Firstly, a Fault Tolerant Control (FTC) technique is implemented. The FTC is based on implementing two new Space Vector Pulse Width Modulation (SVPWM) besides using Field Oriented Control (FOC) to minimize the Torque ripple and to maintain the performance post the two-phase failure. Secondly, Algorithms are proposed to obtain the saliency position post the failure of the two phases. The Technique is based on measuring the transient response of the motor's remaining healthy currents due to the inverter switching actions. These switching actions are related to the PWM signals obtained from the new SVPWM techniques implemented post the two-phase failure. The whole control technique post the failures is very simple to implement. Simulation results are provided to verify the reliability of the proposed control technique to maintain the performance of the fivephase motor drive post the failure in the two phases and the failure of the speed sensor occurred simultaneously without compromising the preperformance (maintain the torque ripple less than 3.6 % and 3.4% post the failure). Moreover, the results have demonstrated the ability for the whole system to work effectively over a wide speed range and load conditions post the failure.
