Stator Inter-Turn Fault Detection and Fault Tolerant Control in DTC Induction Motor Drives using an Extended Kalman Filter
Original language description
This research report presents a fault detection model with fault tolerant control, that allow the system to continue operation in the presence of faults, for a stator inter-turn fault in DTC induction motor drives. The behaviour of a DTC drive in the presence of inter-turn short circuits is evaluated, which makes it possible to offer this technique for the detection of this type of fault. The fault detection is obtained by calculating a new fault indicator based on state and fault parameter estimation of the machine using an extended Kalman filter. Direct Torque Control (DTC) uses the stator resistance of the machine for the estimation of stator flux. The variation of stator resistance, due to stator winding turn fault, creates an error in the estimated stator flux and estimated electromagnetic torque. The fault tolerant control is obtained by estimating the stator resistance using the fault severity factor, estimated with the designed extended Kalman filter, to make the drive more robust and precise. The proposed model is simulated in Matlab/Simulink. The obtained simulation results show the effectiveness of the proposed technique.
