| Abstract |
Operation of a sensorless indirect rotor flux oriented machine in the field weakening region requires
that the variable degree of main flux saturation is recognised and compensated in both the controller
and the estimator. The paper proposes a modified version of the rotor flux based MRAC type of speed
estimator, that fully compensates for the variable degree of main flux saturation. The estimator is used
in conjunction with an appropriate modified indirect vector controller, that accounts for saturation as
well. Effectiveness and accuracy of the developed sensorless vector control scheme for operation in
the field weakening region are verified by extensive simulation. |
