“…It could be useful in order to alert the user of the occurrence of a fault or to implement a specific fault control using the supplementary DoF of the system in order to improve its performance in faulty mode by reducing current amplitude or torque oscillation for example. Among the numerous existing FDI approaches presented in [15–23], the proposed FDI process belongs to a family based on the specificity of multiphase drives. For a n ‐phase machine, the phase currents can be projected in independent planes and axes.…”

This paper investigates a real-time fault diagnostic of a transportation system which needs two drives with faulttolerance capabilities. Because of constraints on the mass of the system and on the cost of the Voltage Source Inverter (VSI), a drive with two Six-Phase Permanent Magnet Synchronous Machines (PMSM) in series-connection supplied by two six-leg inverters is chosen. Despite the serial -connection, independent control of the two machines and fault -tolerance to openswitch fault is ensured. Nevertheless, a Fault Detection Identification (FDI) process is required for analysis and/or control reconfiguration. The proposed FDI is based on the combination of different criteria obtained from the two zero-sequence currents and from the normalized currents mapped into two frames defined by the Concordia Transformation. Results obtained from simulation and experimental tests show the effectiveness of the proposal.

“…Although the proposed method is for diagnosing low‐speed faults of induction motors, discrete wavelet transform provides help for this article. In [26], open‐circuit faults in six‐phase PMSM used in aerospace are classified. The simulation results show that open‐circuit faults can be diagnosed based on the basic space vector trajectory features.…”

“…The obtained results illustrate that the diagnosis speed of the proposed algorithm is fast, and the quantisation of 27 inverter open‐circuit faults is specific. Compared with the methods proposed by [22, 26], it summarises all open‐circuit faults in detail and does not require any motor parameters. However, this method needs to be improved when used to detect the open‐circuit faults of six‐phase PMSM.…”

In this paper a robust vector control method based on second order Super Twisting Sliding Mode Controllers (STSMCs) for two series-connected Five-Phase Permanent Magnet Synchronous Motors (FP-PMSMs) supplied by a single five-leg inverter is suggested. The vector control method of the two seriesconnected FP-PMSMs is based on six regulation loops for currents and speeds that are usually based on proportional integral controllers. Thus, the first aim of this paper is to replace the proportional integral controllers by the proposed second order STSMCs in order to enhance the control system performance in terms of robustness under uncertainties, external disturbances and tracking accuracy. Indeed, the second order STSMCs are proposed in order to overcome the limitations of the proportional integral controllers in terms of sensitivity against the variations in FP-PMSMs parameters and load disturbances and to overcome the first order sliding mode control chattering problem. However, the suggested second order STSMCs require information about the load torques applied to the two FP-PMSMs, which are estimated using sliding mode load torque observers hence reducing the cost and maintenance rate of the electromechanical system due to the elimination of load sensors. Our simulation studies conducted in MATLAB/Simulink check whether the proposed topology of the two series-connected FP-PMSMs controlled by the suggested vector control based on second order STSMCs can regulate the speed at the same time under various conditions. These conditions include load disturbances, parameter variations in both machines, and disturbances resulting from the opening of a phase. Our objective is to demonstrate the excellent robustness of the suggested second order STSMCs based vector control approach in terms of independent speed control of the two FP-PMSMs even at low or reversed speeds, compared with the conventional proportional integral control strategy. In this comparative study, various performance indices are used to demonstrate the robustness of the proposed vector control method based on second order STSMCs control strategy in comparison to the vector control method based on proportional integral controllers.INDEX TERMS Five-phase PMSMs; vector control strategy, second order sliding mode control; supertwisting algorithm, faulty operation modes.
