Abstract
Induction motor has increased its importance in industry over the last two decades, thanks to its robustness and control performance improvement. Direct torque control (DTC) has been the base for multiple developments or modifications in control algorithms and models obtaining great performances against torque variations at any motor speed (including zero speed). In this chapter, DTC scheme is chosen as the starting point to design a fault-tolerant control for induction motors. Also, a study of the possible faults and solutions in the inverter–motor set is presented. The control algorithms used for open-switch and open-phase faults are developed and their results are presented. The supervisor and fault diagnosis system is not included in this work though they were taken into account during the research process.
