Fault-Tolerant Sensorless Control for Six-Phase PMSM with Dual Back-EMF Observer
2022 International Symposium on Power Electronics, Electrical Drives, Automation and Motion (SPEEDAM), 2022The paper deals with the sensorless control strategy used as a sensor backup for safety-critical applications. The sensorless control strategy is realized through a redundant extended Back-EMF observer structure applied to an asymmetrical six-phase permanent magnet synchronous machine (PMSM), controlled by a standard field-oriented control.

Fault-tolerant method for six-phase PMSM by adjusting phase angle
2017 20th International Conference on Electrical Machines and Systems (ICEMS), 2017With the rapid development of electric vehicles, fault tolerance requirements of the motor used in electric vehicles become higher and higher. Multi-phase permanent magnet synchronous motors (PMSM) with their low torque ripple and high reliability and other advantages gradually become the main choice of electric vehicle drive motor.

Research on Vector Control and PWM Technique of Six-Phase PMSM
Advanced Materials Research, 2012The mathematic model that based on decoupling vector space for six-phase permanent magnet synchronous motor (PMSM) is established. The six-phase PMSM is designed with two sets of Y-connected windings phase shifted by 30 electrical degrees. In the model, the variables of the motor are mapped to the α-β subspace associated with the electromechanical ...

Research on Symmetrical Six-Phase PMSM Two-Motor Inversed-Series Connection System
2019 22nd International Conference on Electrical Machines and Systems (ICEMS), 2019By connecting two symmetrical six-phase PMSM in a inversed-series mode, a new series-connected drive system is obtained. The voltage and flux equations in the natural coordinate system are established. Then the voltage and flux equations are transformed into three mutually orthogonal subspaces by decoupling transformation matrix.

Design and analysis of six-phase fault-tolerant PMSM for electric vehicle
2016 Prognostics and System Health Management Conference (PHM-Chengdu), 2016Motor is the sole power source of electric vehicle, whose reliability and fault tolerance are directly related to the performance of electric vehicle. Considering the motor can't keep constantly normal operation as one-phase open-circuit fault occurs, six-phase permanent magnet synchronous motor (PMSM) with fault tolerance is designed in this paper ...

A hybrid direct torque control scheme for asymmetric six-phase PMSM drives
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017In this paper, a novel hybrid DTC scheme is proposed for asymmetric six-phase PMSM drives, which can achieve faster dynamic response of classical ST-DTC scheme and good steady-state performance of classical SVM-DTC scheme. The key is that a completely novel control strategy for torque and stator flux is designed.

Suppression of Steady-State Errors in Predictive Current Control of Six-Phase PMSM Drives
2020 International Conference on Smart Energy Systems and Technologies (SEST), 2020Due to their fault-tolerant capabilities, multiphase machines are a good candidate for application in electric drives where the reliability is a key factor. Recently, finite control set model predictive control (FCS-MPC) has been applied to multiphase drives as it provides good dynamic performance, however it cannot provide zero steady-state errors in ...

Fault-Tolerant Predictive Control of Six-Phase PMSM Drives Based on Pulsewidth Modulation
IEEE Transactions on Industrial Electronics, 2019Multiphase machines are famous for their fault-tolerant capability. Conventional fault-tolerant model predictive current control (FT-CMPC) of multiphase machines suffers from high computational burden, low switching frequency, and relatively high current harmonics.
