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 Torque Control of an induction motor drive. Influence of the speed sensor faults to the properties of the DTC-SVM drive system is presented. Control structure with and without outer speed control loop is analyzed. Simple algorithmic mechanism of the speed sensor fault detection is described. During the faulted conditions vector controlled drive is switched...
