Comparative Study of DTC and RFOC Methods for the Open-Phase Fault Operation of a 5-Phase Induction Motor Drive
TypeCommunications avec actes
Direct Torque Control (DTC) technique has been applied in recent times in high performance five-phase induction motor drives during the normal operation of the system. The use of DTC in the multiphase area is far from becoming a reality because it has not been used in competitive multiphase applications where the fault operation needs to be considered. The authors have successfully tested the ability of DTC controllers to manage the open-phase fault operation in a five-phase induction motor drive. However, the conclusion of the mentioned study must be completed comparing the obtained results with other mature alternatives based on field oriented controllers. This paper focuses on the comparative analysis of DTC and Rotor Field Oriented Control (RFOC) when an open-phase fault appears in the five-phase induction motor drive. Simulation results are provided to compare the performance of the system using these control alternatives.
