Abstract :
In present paper feedback linearization approach for induction motor control in flux - weakening region is proposed. Steady state equations of rotor flux feedback linearization control (FLC) are used for selecting optimal air gap flux level permitting maximum torque operation in field - weakening region. By adjusting the base speed for the constant power operation according to the air gap flux level, the current limit and the voltage limit can be achieved. Preliminary simulation results are presented.
