Abstract
The effects of sensor faults on motor variables and control performance in induction motor drives are analyzed by both theoretical approach and simulation study, Vector control and direct torque control method for induction motor are well known. To control speed or position, the informations on rotor speed and rotor or stator flux are required in these control algorithms. The speed is measured by encoder. and the rotor or stator flux is estimated using motor parameters and measured currents. The control input generated based on the information from a faulted sensor should be far from the desired value and deteriorates the overall control performance.
