Postfault Direct Field-Oriented Control of Induction Motor Drive Using Adaptive Virtual Current Sensor

Michal Adamczyk et al.

Summary: This article discusses the analysis of a direct field-oriented control induction motor drive after the failure of all stator current sensors. An adaptive virtual current sensor (AVCS) is used to estimate the stator current based on the measurement of the motor angular velocity and the voltage in the DC of the voltage-source inverter. The article presents the possibility of improving the accuracy of stator current estimation using the original approximation of changes in rotor resistance depending on the drive operating point.

Sensorless control of a PMSM drive post an open circuit failure based on 3D-SVPWM technique

Kamel Saleh et al.

Summary: This paper presents a novel technique to maintain the operation of a PMSM drive in the event of a failure in one phase and the speed sensor simultaneously. The technique utilizes a fault-tolerant inverter and a 3-Dimensional space vector pulse width modulation (3-D SVPWM) to ensure the performance of the drive post the failure. Additionally, a novel algorithm is employed to determine the rotor position and speed based on the transient response of the remaining healthy currents, enhancing the stability of the drive system.

Maximum Torque per Voltage Flux-Weakening Strategy With Speed Limiter for PMSM Drives

Carlos Miguel-Espinar et al.

Summary: This article introduces an enhanced flux weakening control scheme for permanent magnet synchronous motors in electric vehicle applications, which integrates the accelerator pedal and cruise speed limiter in a unified framework. The proposed algorithm utilizes polar coordinate and per-unit systems to calculate dq-axis current references, based on machine parameters for simplified implementation. The scheme also allows for smooth transition between different operating conditions without switching algorithms, verified through simulations and experiments on a real e-motorbike.

Winding Condition Monitoring for Inverter-Fed PMSM Using High-Frequency Current Injection

Zheng Xu et al.

Summary: This article proposes a winding condition monitoring scheme for inverter-fed PMSM based on high frequency current injection, which shows high sensitivity to inter-turn short-circuit faults (ISF) and negligible sensitivity to PMSM operation conditions. The method can accurately identify ISFs in one phase as well as multiple phases, and has been validated through simulations and experiments.

Sensorless Predictive Current Control of PMSM EV Drive Using DSOGI-FLL Based Sliding Mode Observer

R. Sreejith et al.

Summary: This article discusses a sensorless speed and position estimation technique for a surface mounted permanent magnet synchronous motor (SPMSM) based electric vehicle (EV) drive using a sliding mode observer (SMO) with a dual second order generalized integrator frequency locked loop (DSOGI-FLL). The method of utilizing the DSOGI-FLL, along with feedforward term, is shown to achieve better harmonic elimination of estimated back EMF components and faster dynamic speed estimation. The system is simulated using Simulink and experimentally validated using dSPACE 1202, demonstrating better performance compared to the conventional technique.
