The principle of vector control of AC machine enables the dynamic control of AC motors, and induction motors in particular to a level comparable to that of a DC machine. The vector control of currents and voltages results in control of spatial orientation of the electromagnetic fields in the machine and has led to term field orientation. Field oriented control schemes provide significant improvement...
This contribution deals with design of sliding mode based stator flux observer for direct torque and flux controlled induction machine drives. Proposed flux observer is completed by simple estimation of rotor speed in order to achieve a sensorless drive control. Proper function of presented sensorless control is verified by both simulations and experiments made on designed laboratory prototype of...
