Current Sensor FTC Method for MPTC of Three-Phase Induction Motor Drives Without Speed Measurement

In encoderless Model Predictive Torque Control (MPTC) of three-phase Induction Motor (IM) drives, current sensors can face different electrical or mechanical faults in harsh industrial environments. this research, single-phase sensor Fault-Tolerant (FTC) method for MPTC IM drives without speed measurement using a flux linkage observer and Reference Adaptive System (MRAS) algorithm is proposed. the presented FTC method, Third-Difference operators, logic circuit module, observer, MRAS are utilized fault detection, isolation, estimation stator currents fluxes, estimation, respectively. comparison with conventional methods, proposed be drives. order to confirm usefulness possibility experimental studies performed 0.75 kW drive system situations. The achieved results demonstrate good performances technique during both normal faulty
