Abstract
A new sensorless controller based on direct torque control, for a sync hronous machine is proposed. Using direct torque control, stator resis tance is the only parameter of the machine which should be known. The use of reactive torque control simplifies the field current control lo op. Initial stator induced currents are used to estimate the initial s tator flux. The outputs of the control system are switching commands o f stator inverter and rotor chopper.
