“…However, most of these studies focused on developing control techniques for multi-phase (more than three phases) electrical machines under open-phase fault(s). [6][7][8][9][10] The present study focuses on a control system for a starconnected TPIM (SCTPIM), which is the most dominant type of motor used in many industries.…”

The present study aims to propose an indirect field-oriented control (IFOC) strategy for star-connected three-phase induction machine (SCTPIM) drives against singlephase open-circuit fault. In the proposed IFOC method, transformation matrices (TMs) are applied to the faulty SCTPIM equations. Based on the results, the asymmetrical equations of the faulty SCTPIM can be transformed into symmetrical equations by using these matrices. The symmetrical equations have structures which are similar to healthy SCTPIM equations. Thus, a midfield IFOC strategy could be shared during both normal and open-phase fault operations. The performance of the proposed control system was confirmed based on the simulations and experiments for a vector controlled 0.75 kW SCTPIM drive. The results confirmed the effectiveness of the introduced controller in the speed and torque ripples decreasing of the faulty SCTPIM and eliminating the unbalances in the faulty SCTPIM currents.

“…The PR or PI controllers could be implemented in per-phase stationary coordinates, as opposed to VSD. This approach is adopted, for example, in [66,[148][149][150][151] with PI control, in [63,[152][153][154][155]242] with PR control, and in [156,157] with a combination of both. Since high gain is thereby included for all current DOFs, tracking/rejection of unbalanced references/disturbances is achieved.…”

Multiphase machines are very convenient for applications that require high reliability. In this two-part survey, the state of the art about fault tolerance in multiphase drives is reviewed. In Part 1, an overview including numerous fault types was presented, along with fundamental notions about multiphase drives. Here, in Part 2, the focus is placed on phase/switch open-circuit (OC) faults in particular, which have received the most attention in the literature. Phase OC failures involve OCs in stator phases or in converter-machine connections, and switch/diode OCs are frequently dealt with similarly or identically. Thanks to the phase redundancy of multiphase drives, their operation can be satisfactorily continued under a certain number of OCs. Nonetheless, the procedure to follow for this purpose is far from unique. For given OC fault conditions, numerous fault-tolerant possibilities can be found in the literature, each of them with different advantages and disadvantages. Moreover, a great variety of methods have also been devised to detect and diagnose phase/switch OC failures so that, as soon as possible, the most appropriate fault-tolerance measures are applied. Thus, given the broad literature about tolerance to phase/switch OC faults in multiphase drives, the survey presented here is expected to be of great interest for the research community and industry.

“…The manual and automatic speed control of FPIM drive has been obtained by open‐loop and closed‐loop speed control, respectively. The FOC, DTC, and sensorless control are implemented through digital signal processors [18, 19] This paper proposed an FPGA‐based speed control of FPIM drive and also measured the power quality factors such as voltage and current harmonics, Crest factor, unbalancing, short‐term and long‐term flickering, K‐factor, real, reactive, and apparent power, power factor in open‐loop control. This paper compares the response of FPIM drives at a closed‐loop in both PID and DTC techniques.…”

Here, a novel control technique for Five‐Phase Induction Motor (FPIM) drives using a field‐programmable gate array (FPGA) controller is proposed. Open‐loop control is analysed in terms of the performance and measurement of various power quality factors, such as voltage harmonics, current harmonics, total harmonic distortion, crest factor, unbalanced, short and long‐term flickering, K‐factor, real power, reactive power, apparent power, and power factor. This study experimentally demonstrated a closed‐loop system with both PID and DTC controls for the FPIM. Diminished torque pulsation is obtained by efficiently utilizing the voltage vectors from the total states of 25 = 32. A novel EG voltage vector sequence was proposed for DTC techniques and compared with small, medium, and large voltage vector sequences. Proposed innovative control programming techniques in spartan‐6 XC6SLX25 series FPGA for switching the five‐phase two‐level inverter to reduce the total harmonics distortion by less than 2%.
