In the paper the analysis of the Fault Tolerant Control (FTC) of Induction Motor drive system is presented. The Direct Field Oriented Control was used for analysis the speed sensor faults detection systems based on the simple mathematical relationship with two types of the rotor speed estimators. In the diagnostic systems and in the post faulted conditions the MRASCC and NFO observers were used. Simulation...
In the paper a comparative analysis of the two detectors of the rotor speed sensor faults are presented. The first one is based on the MRAS estimator (Model Reference Adaptive System) and the second one is based on artificial neural network. Performance analysis of each identification and detection system in different operation conditions in the Direct Field Oriented Control structure DFOC is presented...
