“…The most significant disturbances that affect the accuracy of MRAS-SM observer and the performance of the FOC technique are the motor parameters variations. In practice, the motor resistances vary with the change of the temperature which means stator resistance s R and the rotor resistance r R deviate from their nominal values or initial values, as it is shown clearly in (12), s R value has important role in the reference model therefore its value should be known with good precision to obtain an accurate estimation of the stator flux components. In the same context, the FOC technique is dependent on the rotor parameters ( r R or r T ) [34].…”

“…These features have made OESW variable speed drives with dual-VSI suitable for different high power and emerging applications, such as rolling mills [10], and electric vehicles and hybrid electric vehicles [11]. The concept of OESW topology has been recently applied to systems with a higher number of phases such as five- [7] six- [12], seven-, and nine-phase [13]. Therefore, this concept has motivated the authors to adopt this topology.…”

This paper proposes a sensorless field-oriented control (FOC) of an open-end stator winding five-phase induction motor (OESW-FPIM). The FOC technique used is associated with dual Space Vector Modulation (SVM) to provide a constant switching frequency and lower harmonics distortion. Furthermore, a simple hybrid observer is proposed which combines a model reference adaptive system (MRAS) and a sliding mode (SM) observer. The examined observer is designed for the estimation of the rotor flux and rotational speed as well as for the estimation of the load torque disturbances. Lyapunov theorem is used in this paper to prove the observer's stability. The work presented in this paper aims to enhance the researched motor's sensorless control and its robustness against external load disturbances and parameters variation. In the proposed MRAS-SM observer, the reference model is replaced by a SM model which uses a sigmoid function as a switching function to overcome the chattering problem. This combination is intended to make use of the advantages of both strategies. At the same time, to preserve the high-level performance of the sensorless FOC technique and to reduce system uncertainties, an estimation algorithm is developed to identify the rotor resistance and the stator resistance simultaneously during motor operation. The parameter estimation algorithm is combined with the proposed control to improve the speed estimation and control accuracy, particularly at low-speed operation. Finally, the effectiveness of the proposed control is validated in real-time by utilizing a hardware-in-the-loop (HIL) platform.INDEX TERMS Field-oriented control, five phase induction motor, parameters estimation, MRAS estimator, sensorless control, sliding mode observer.

“…Therefore, it appears that multiphase machines are a strong competitor, especially in demanding high-power applications like aerospace, electric aircraft, railway traction, wind-energy conversion, ship propulsion, and other industrial applications where great reliability and redundancy are essential [9,[14][15][16]. Due to these inherent benefits, it is feasible to combine the advantages of both structures by just using the open-end winding (OeW) structure with multilevel inverters for multiphase motor drives [2,4,5,7,[17][18][19][20][21][22], where the desired configuration can be achieved by opening the neutral point of the 5PIM drive and powering both ends of the windings of the stator with a dual inverter. Due to the various benefits it possesses over a star-connected machine, the OeW design has attracted interest because of its features, such as its lower voltage stress on power switches, reduced dc-link current, multi-level waveform, higher power 1.…”

Experimental Validation of Different Control Techniques Applied to a Five-Phase Open-End Winding Induction Motor

Open-end winding five-phase induction motor (OeW-5PIM) configuration is used in industrial applications, where minimization in the total harmonic currents and high reliability are needed. The majority of the literature on OeW-5PIM topology discusses field-oriented control and direct torque control in addition to other robust control techniques such as the backstepping approach. This paper focuses on the mathematical and experimental approaches of backstepping control (BSC) and rotor-flux-oriented control (RFOC) for an OeW-5PIM topology. The space vector pulse width modulation (SVPWM) strategy is associated with the suggested control techniques to improve the dynamic performance (i.e., reducing ripple, fixed switching frequency, etc.) of the studied motor. Furthermore, the RFOC-SVPWM and BSC-SVPWM are comprehensively compared using experimental implementation under various situations such as load torque, open-phase fault, and high/low-speed operation.

“…However, in high-power applications, the filter has a large volume and is not flexible enough. Unlike the filter, the output waveform can also be more sinusoidal by increasing the levels of the inverter [5,6]. The common topologies of a multilevel inverter have a flying capacitor, neutral point clamped and cascaded Hbridge [7].…”

Among the existing harmonic current suppression methods, it is difficult and complicated to suppress any nth harmonic current accurately for multi-phase permanent magnet synchronous motors (PMSMs). To solve this problem, this paper takes a five-phase dual-rotor PMSM fed with a current source inverter (CSI) as an example, and proposes an nth harmonic current suppression method based on the impulse current PWM algorithm. Firstly, the analysis is conducted and presented for the nth harmonic current in the mth harmonic space. Then, based on the Sliding Discrete Fourier Transformation (SDFT), a low-pass filter (LPF) named SDFT-LPF is designed. Additionally, the impulse current PWM technique for the five-phase CSI is realized. In this paper, the experiments have confirmed that the SDFT-LPF has good filter performance. Compared with the SVPWM, the impulse current PWM technique has the same DC-link current utilization rate, but it is easier to implement. Moreover, the proposed harmonic current control method can accurately control any nth harmonic current without changing the PWM technique, which has significantly reduced the complexity of the harmonic current control. Additionally, the proposed scheme is easy to implement and can be directly extended to the multiple harmonic current’s control.
