Modified voltage model flux estimator and current model flux estimator are employed in estimation of stator flux linkages of the motor. The developed torque is then calculated based on the estimated flux linkages.Threeleg inverter is employed in the postfault operation and a switching table is designed subjected to the topology. Performances of the systems using different flux estimation are compared. Developed torque and stator flux linkages of the faulty motor are regulated and at a constant torque operation stator currents are automatically developed to stabilized the system.Performances of the systems are verified by experimental results.||URI:||https://scholar.utcc.ac.th/handle/6626976254/3558||Rights:||This work is protected by copyright.
