The paper deals with the fault tolerant Direct Field Oriented Control (DFOC) of an induction motor drive. Influence of the stator current sensor faults to the properties of the DFOC drive system is presented. To the current sensor fault detection the simple algorithmic/logical mechanism, based on the measured currents is used. After the fault detection, drive topology is changed. For the calculation...
The paper deals with the fault tolerant Direct Field Oriented Control of an induction motor drive. Influence of the stator current sensor general failures to the properties of the drive system is presented. To the sensor fault detection the artificial neural network approach is proposed. After the fault detection, drive topology is changed based on the sensor or control topology redundancy. Drive...
