Abstract :
The universal field-oriented controller is used to control induction motor torque and airgap flux independently of each other. The decoupling equations of the universal field-oriented (UFO) controller are identical for both direct and indirect field orientation. In this paper, a UFO controller is described that can operate both in a direct or indirect field orientation mode, allowing transitions from one mode to another. The proposed field-oriented controller can be realized at minimal cost in AC servomotor drives requiring motion control or accurate speed control
