TL;DR: Using this approach, it can be verified that the space-vector modulation technique, owing to the intrinsic two degrees of freedom, represents the general solution of the modulation problem of matrix converters.

TL;DR: In this paper, a fault-tolerant control scheme for multiphase induction motor drives is presented and assessed, which is valid either in transient or steady-state operating conditions.

TL;DR: Two open-phase fault-tolerant control schemes are experimentally compared in a real five-phase induction machine and it is shown that predictive control provides faster control response and superior performance at low-speed operation but is found to be less resilient to fault detection delays and to have higher current ripple.

TL;DR: Simulation and experimental results show the validity of the proposed method, leading to an effective diagnosis procedure for both stator and rotor electrical faults in WRIMs, and proves the importance of the fault components computed from rotor voltages in comparison to those coming from rotor currents under closed-loop operation.

TL;DR: In this paper, the stator flux components were used as control variables for a speed-sensorless induction motor drive to achieve a constant-switching-frequency operation, where the required voltage vector was calculated on the basis of the error between the reference and the estimated stator vector.
