Abstract

The paper deals with faults diagnosis and control methods for a fault-tolerant direct field-oriented controlled by Space Vector Modulation (SVM) two-level voltage-inverter-fed induction motor drive. In order to maintain an uninterrupted motor drive operation even under its faulty condition, two diagnostic algorithms as well as post-fault control techniques are developed. According to the first diagnostic system, that is related to single open-circuit faults in two-level voltage inverter, a failure diagnosis is performed by monitoring a time presence of a reference inverter voltage vector in particular sectors of the α–β coordinate system. After the fault detection, to maintain a high-quality drive performance, a switch-redundant inverter scheme is utilized. In case of the second diagnostic system, for the speed sensor failure detection, a motor speed estimator, that is based on a model reference adaptive system, is utilized. This algorithm is used for the post-fault motor drive operation as well. Both fault monitoring methods are based on a software solution, therefore they do not generate additional implementation costs.
